HOW-TO
How to generate a wheel STEP / STL file
- 1Enter wheel diameter, tire thickness and width.
- 2Set bore type, hub and lightening holes.
- 3Check the spec cards and any warnings.
- 4Download STEP, STL or 3MF — or send it to Orinovate for a quote.
Wheel construction
Tire, rim, disc and hub are fused into one solid: the tire has rounded edges, the disc has adjustable thickness and lightening holes, and the full-width hub takes a round, D-cut, keyway, hex or square bore.
Design tips
Robots and small rovers typically use ⌀40–⌀100 mm wheels with width about ¼–⅓ of the diameter. Lightening holes save material and print time; keep a thicker disc for load-bearing wheels.

FAQ
What shaft does a yellow TT gear motor have?
A double-D shaft about 5.4 mm across with ~3.7 mm between flats. The D-cut here has one flat at 0.9·d; enlarge the bore by 0.1–0.2 mm if the print is tight.
How far does the wheel travel per turn?
π × diameter. A ⌀65 mm wheel moves ~204 mm per revolution; at 200 rpm that is ≈ 0.68 m/s.
How do I add grip to a printed wheel?
Print the tire separately in TPU, or stretch an O-ring or rubber band over the rim. All-PLA wheels work but slip on smooth floors.
Which software opens the wheel STEP file?
STEP (AP214) opens in Fusion 360, SolidWorks, FreeCAD, Onshape and Rhino. STL / 3MF import directly into Bambu Studio, PrusaSlicer or Cura.

About STEP / STL / 3MF / DXF
- STEP (.step / .stp, AP214) keeps exact dimensions and surfaces for editing in Fusion 360, SolidWorks or FreeCAD.
- STL and 3MF are triangle meshes that import directly into Bambu Studio, PrusaSlicer or Cura.
- DXF is the top-view 2D outline, ready for laser cutting, waterjet or CNC routing.
- All models are in millimetres at true scale.
