Print and Fly incl. Printing Solutions

Included in the download:

  1. OWLplane model STL files.
  2. G-code using PLA or LW-PLA type of filaments (depending on models) with Prusa i3 Direct Driver and/or Bowden type Printer.
  3. ideaMaker, Cura and S3D OWLplane Profile files for 0.3mm and 0.4mm Nozzles for PLA model series, both DD and Bowden type printers. For LW-PLA/ “Digital Balsa and Foam” series, both nozzle sizes (0.3mm and/or 0.4mm) and Direct Drive or Bowden type of printers use the same Profile files due to LW-PLA filament specific characteristic when printing. For “Digital Balsa and Foam” series, S3D is replaced with PrusaSlicer slicers due to that there is no gyroid infill patterns.
  4. Instruction Manuals (User, Assembly, Print Guides and Drawings).
  5. Motor Mount, Servo Cover and/or Servo Bridge STEP files for you to customize whenever necessary (subject to the plane model. Please note, in general, OWLplane only share the STL files to print not CAD model source files).

Please check your email on how to download the files after purchasing.

OWLplane have already tested our Models printed with PLA, ABS, ASA and HIPS filaments. OWLplane also provide G-code files if you would like to print directly to your Prusa i3 Direct Drive, Creality Ender 3/5 Families or Others with both Direct Drive/Bowden setup with PLA Filament only. No worry, for other filaments, just change the parameters and slice it again (see PRINT tab above for details). 

For having best results, OWLplane recommend to slice yourself with provided Profile files so that you can adjust/optimize them to suite your own 3D Printer requirement.

From our experience, with optimal extrusion width and layer height, it can reduce the printed plane weight expected about 20-30% (for all filaments stated above) from commonly standard Profile file printed with PLA filament.

OWLplane provide Animation and Assembly Videos on how to assembly all OWLplane RC Models so that you can see and learn from the Youtube Videos. More details might not be shown in the Animations and Assembly Videos but will be provided in this website pages and also in the Instruction Manuals.

Congratulation !

You should be ready to fly your plane. But, make sure the CG is correct, the Control Surfaces are well setup, the Motor Power is suitable to fly, etc.

We offer 3D printed RC plane models to print with your 3D printer at home (note : not the CAD source files). Once you have downloaded, you can start printing your plane with filaments that you choose such as PLA, ASA, ABS, HIPS and LW-PLA (note: not all parts are suitable printing using LW-PLA/ePLA-LW and depending on the models). Profile files are provided for your Direct Drive and Bowden printer setup for both 0.3mm and 0.4mm nozzle but only for PLA and/or LW-PLA (for other filaments, just update the temperature Profile files accordingly and follow manufacture setting recommendation).

G-code files are provided for you to start with both 0.3mm and 0.4mm nozzle. If you have 0.4mm Nozzle, you may want to try G-code files for 0.3mm nozzle and see if the Nozzle still can print with acceptable quality.  You may notice that the result will have 20% – 30% less weight with regular PLA or PLA+. LW-PLA filament can be printed with both 0.3mm and/or 0.4mm nozzle.

3D Printer volume min. requirement is 200mmx200mmx200mm.

Nozzle size is 0.30mm – 0.40mm, best with 0.30mm for PLA. No difference when printing with LW-PLA for both 0.30mm and/or 0.4mm nozzle.

Only LW-PLA and “Digital Balsa and Foam” model series should be printed with LW-PLA type of filament.

Slice with Your Favorite Slicers Below

Provided Profile Files :

Version 4.8.0

Version 4.0.1

(do not use ideaMaker software for Prusa printers since M221 command to change the flow rate is ignored by the printers)

Version 4.1.2

(replaced with PrusaSlicer for “Digital Balsa and Foam” series but the new release Version 5.0.1 can slice with Gyroid type of infill. If you have Version 5.0.1, still can use the slicer)

Version 2.5.0

(available for “Digital Balsa and Foam” series only, not yet updated for standard profiles but it can slice them correctly)

ideaMaker is free Slicer Software recommended to use for slicing OWLplane STLs beside Cura since there is also no cost to acquire, it has similar interface and feature required to change parameters on specific layers like S3D. For paid one, S3D (Simplify3D) is recommended to use. Click read more hyperlink below for more information.

Initially, OWLplane only utilize S3D during development time. After having experience utilizing ideaMaker, both S3D and ideaMaker Slicers are used since both having the same required features and easy to use. In short, S3D has better preview on sliced object where ideaMaker has better user interface/workflow for working on different Profiles in OWLplane subjective opinion.

If you have not invested in S3D, OWLplane highly recommend to use ideaMaker instead, no difference from slicing OWLplane 3D Printed Plane and its free ! No worry, if you have invested your time and your favorable slicer is Cura, OWLplane provide Cura Profiles and STL file modifier to use for slicing OWLplane STL files. It can slice what ideaMaker and S3D also slice with utilizing STL file modifier,

Cura is another excellence free slicer. Unfortunately, Cura is not as easy to use when requiring feature like it has in ideaMaker and S3D for creating different setting for layers. ideaMaker uses “Layer Group Settings”, S3D uses Processes and Cura uses object modifier or support blocker technique. In cura, you have to modified object instead of by adding/updating/introducing some settings. It is not as convenience as ideaMaker and S3D in OWLpane subjective opinion. Dont get us wrong, OWLplane also support Cura.

Feel free if you still want to use Cura instead. It also works without any issue.

By reducing extrusion width to below .40mm and it is also suggested to replace your nozzle from 0.40mm down to 0.30mm nozzle. No worry, 0.30mm nozzle is still able to print extrusion width with more than 0.4x extrusion width.
PLA still can have decent strong result by lowering extrusion width comparing to ABS since its material property is stronger than.


Since the extrusion width gets reduce, it means that need also to reduce the layer height also. Since, it will get more contact surface areas from layer to layer to compensate.


The benefit of ABS, ASA and HIPS is that you can print with the same extrusion width and layer height as PLA settings but can get benefit of less weight since their densities are about 20% lower comparing to PLA. They are also more heat resistance comparing to PLA.

"Reducing Extrusion Width means that you need also to reduce Layer Height to keep strong layer to layer adhesion"

OWLplane uses "Strength Level Code" as depicted on the left side table for easy to track the strength and weight comparison

Feel free to experiment with Strength Level Code -1 parameters for ABS (also ASA, HIPS), since it really depends on the filament quality

For your consideration, the benefit of taking 20-30% printed weight off is about the same weight as the rc plane battery itself. All OWLplane Models have been tested successfully with 0.30 extrusion width and 0.17mm layer height for PLA (Strength Level Code L0) and with 0.38 extrusion width and 0.2mm layer height for ABS (Strength Level Code L1). 

Optimizing Your Printed Result Some Suggestions (Applies Only for Non LW-PLA Filaments)

Starting with 0.32mm Extrusion Width for PLA (continue optimizing from that value).

Hints for 0.4mm Nozzle: 

  • For PLA Filament : Set to Strength Level Code L3 instead as your default/start value (or 0.40mm for extrusion width and 0.20mm for layer height) if it can not print with decent result with Strength Level Code L1. 
  • For ABS Filament : Strength level Code L1 should be ok (OWLplane default value), increase gradually when print quality is affected by 0.4mm Nozzle

finding optimal setting values to get optimal weight and strength

Start with default Strength Level Code and optimize the values from there to get benefit of optimal weight with adequate strength level. Visit Print tab page for more information.

Optimizing Some Parameter Values

You may need also to review print quality not just strength level. Visit PRINT tab above and select PRINTING AND SETTINGS SOLUTIONS page for more information.


Figures above are for your reference. FUSELAGE-2 # P3_H15 from OWL MDM-1 Fox plane model is printed with commonly standard Profile settings and the weight is measured 46g as seen on the right side both figures as reference. Printed with PLA filament, extrusion width 0.42mm, layer height 0.25 and extrusion multiplier 1.02. If you would like to prove it, just download the provided Test Files and play with them.

The results are as follow:

  • PLA: Strength Level Code L1 and L0 are 36g (22% lighter from ref.) and 32.5g (29% lighter from ref.) respectively.
  • ABS: Strength Level Code L3 and L0 are 41g (10% lighter from ref.) and 33g (28% lighter from ref.respectively.

Alignment and Guide Tools

With Alignment and Guide Tools, the assembly process is much easier and faster. Moreover, it can be stronger due to correctly aligned and also as support.

Reuse Your Servos

Utilizing 3D printed Servo Cover and Bridge.


Number of STL Servo Cover files are provided for range of Servo Brands, if none of them fits to your Servo, a STEP file is also provided for your convenience to modify it so that it will perfectly fit with your Servo.

Rod instead of CA or Plastic Hinge

With utilizing Rod, it would be clean and easy Installation. You can use also the rod as guide or alignment assembly tool when gluing the parts. The Rod OD is usually best used with 1.5 or 1.6mm (allow range from 1.2mm – 2.2mm).

Offering Printing Solutions

Three figures below showing bottom, full and top views from left to right respectively. Both bottom and top views have 3 perimeters so that it makes joining surfaces larger comparing to printed with only 1 perimeter at the top layers (see thicker layers at top and also bottom). This printing technique can be found under PRINT tab above on the Printing and Setting Solutions page.

*) This technique is not applicable for “Digital Balsa and Foam” approach.

Please Note : Provided Profile and G-code files for all Models are set with 3 perimeters at the bottom layers only. Adding more perimeters for above layer as shown below is required whenever you feel that you need more surface areas for stronger bonding. 


The solution is by getting help from STL modifier file. Need to change the printer perimeter setting value on the modifier into 2 perimeters and increase material flow by 125% or more. Increasing flow is required so that the printed perimeter touching its next shell. This technique is not perfect since Cura has limitation on tweaking layer per layer settings.


As explained in one of the above section, just use "Per-Layer Settings under Group and Layer Settings" setting. It needs to set gradual increment to form stairs for layers as shown on the left side figure. The Profile and test files are included in the free to download test files.


As explained in one of the above section, just use "Process" setting and also use the same technique shown in ideaMaker solution above.

OWLplane is powered with Gumroad. Is it safe to purchase through gumroad ?

What happen after purchasing OWLplane model ?

Can I print extrusion wiDth 0.4xmm with 0.3mm Nozzle ?

Yes, you still can print. OWLplane have tried printing up to 0.5mm extrusion width with 0.3mm nozzle size and it prints without any issue.

Can I use 0.4mm nozzle SIZE for printing 0.3xmm extrusion width ?

Yes, for certain nozzle condition. It is best if you change the nozzle size to 0.3mm instead.


Please visit the following page to answer the question. Nevertheless, OWLplnae supports Cura. Profile files are already provided also including with STL modifier.

The rod does not fit into printed hole, what should i do ?

Please prepare with some OD options such as 1.5mm, 2.0mm, or others. If still some issues, you may want to try using heated rod so that the rod can enlarge the hole. The second solution, you may want to use Dimensional Compensation Feature to enlarge the hole. Note: make sure the hotend temperature is set for the best. Most of the time, it fits with 1.5mm OD rod.

Use default profile files, found the printed result having scattered SOME small holes?

Check if you use 0.4mm nozzle. If yes, change to strength level L3 (common standard setting values). Please read the section above in this page for the recommended values. The penalty is that you can not have advantage of reducing about 20% of your total printed weight.

Can I print ABS Filament without enclosure ?

You may see common warping issue. It is well understood that ABS needs enclosure to prevent the warping issue. 

Can I still use CURA Slicer ?

Yes, you can. Just use provided Cura Profile files for all OWLplane models. You may need to update the parameters suitable for your 3D Printer to get best results.

do you have solution to tolerance issue (DOES NOT FIT TWO PARTS WELL) ?

Please use Dimensional Compensation feature to fix. You may want to scale up or down a bit your print to fit. Cura, ideaMaker and S3D all have that feature with different names.

Slice the STL but internal structure either not touching the shell or introducing hole, how to fix it ?

It can be fixed utilizing Dimensional Compensation Feature. Please visit this page to know how. Another simple solution is lower or higher the extrusion width and see if it fixes the problem.

How I make layer A to layer B with two perimeters or need to increase extrusion width (for specific strenth need) ?

ideaMaker and S3D are excellent Slicers to change that perimeter settings. You can use Process Feature in S3D or Group and Layer Settings Feature in ideaMaker for it. For example, you may want to set 2 (two) perimeters areas around main landing gear. In Cura, you need to use STL modifier.
