Wing STL generator
Type in your wing and download print-ready STL files: split into sections that fit your printer, with carbon tube channels, printed internal ribs, cut-out ailerons with a hinge bevel, a servo pocket and a wire channel. The same method as our LayerWings planes. Made on your computer, nothing is uploaded.
Print list
Press Make STL files to build the parts.
- Print each section standing on its root face, no supports. Turn it diagonally if it is wide.
- LW-PLA: 2 walls, 0 % infill, 0 top / 0 bottom layers except the first 3 bottom layers. The thin slots become the spar webs and ribs.
- Normal PLA or PETG: 1–2 walls (0.4 mm), 0 % infill. It will be about twice as heavy.
- Ailerons print standing too. The front of each aileron has a V so it can move ±25° on CA hinges.
- Thread the sections onto the carbon tubes in order (L1 at the root) and glue the joints with slow epoxy or CA.
- The tube holes have 0.15 mm clearance for glue. Sand lightly if your printer prints holes small.
- Push a 3 mm carbon rod into the aileron pieces where they meet, so both pieces move together.
- Check the CG of the whole plane with our Design Lab or CG calculator.
Questions
Is the wing generator really free?
Yes. The STL files are made in your browser and are yours for personal use. Nothing is uploaded and there is no sign-up.
What printer and filament does it work with?
Any FDM printer. Set the max section length to a bit less than your printer height (245 mm for a 256 mm Bambu Lab bed, 210 mm for a 220 mm bed). LW-PLA or PLA Aero gives the lightest wing; normal PLA and PETG work too but are about twice as heavy.
How do the printed ribs work?
Each section has thin 0.2 mm slots inside it. With 2 walls and 0 % infill the slicer prints walls on both sides of every slot, which become spar webs along the carbon tubes and diagonal ribs between them. It is the same method as our LayerWings planes.
Which airfoils can I use?
Any NACA 4-digit airfoil, for example 2412 (semi-symmetrical, a good all-round choice), 4412 (more lift), 2410 (thinner, faster) or 0012 (symmetrical). Use at least 9 % thickness if you want carbon tubes inside.
Does it make the fuselage too?
No, only the wing panels and ailerons. Pair them with your own fuselage, or check your whole plane in our Design Lab.
