Changing a dimension today means opening a modeling program. The next step for the platform is letting you tweak the parameters on the page itself and download a file ready to slice. It is not live yet — and we only announce a date once it works.

Gear generatorTeeth, module, diameter, shaft bore and clearance. A pair that actually meshes, not two parts that only look like they match.
Shaft generatorLength, diameter, keyway and bearing seat, with the clearance your machine needs.
Boxes, brackets and spacersThe tedious parts to measure: a box the size of your gear, a bracket with the hole in the right place.

testing is literal

Every file went through a printer before it reached you.

Printed, measured with calipers and photographed on the bench. The 3MF comes with the profile we used, so what you see is what comes out.

3D printing cost calculator: does the part really make a profit?

Enter the weight, the time and the listing price. The math adds filament, electricity, machine time and failures, and shows what is left on Etsy, eBay, Amazon Handmade and your own store.

Try a model:

Electricity at $0.20/kWh, machine time $0.30/h and 10% failures. Reference fees for the US, October 2026: check each platform. The full calculator lets you edit everything.
