Tell it what you're building, with the dimensions and hardware you need. You get a .3mf you can slice and print, tolerances and all.

A mounting bracket generated from a text description

You already know what you need.
CAD is just in the way.

NEMA 17 mounting bracket

You need 4x M3 holes on a 31mm pattern. You shouldn't need to learn Fusion 360 for that.

ESP32 snap-fit case

You know the board dimensions. You just need a box with standoffs and a lid that clicks.

M12 cable gland adapter

A threaded adapter with known specs. 20 minutes in CAD, or 20 seconds describing it.

What's different here

It knows real part dimensions

Say 'NEMA 17' or 'M3 bolt' and it looks up the actual dimensions. Holes end up where they should be.

Tolerances that actually work

You can specify clearances and press-fit requirements. The geometry accounts for them, so stuff fits on the first print.

Easy to change

Want thicker walls or a bigger hole? Just say so. It rebuilds the model instead of making you start over.

Ready for your slicer

You get a clean .3mf with no mesh errors. Download it, slice it, print it.

How it works

1

You describe the part

"Create a mounting bracket for a NEMA 17
with 4x M3 holes, 3mm wall thickness,
and 0.2mm tolerance for press-fit."
2

It looks up real dimensions

NEMA 17: 42.3mm face, 31mm hole pattern
M3: 3.0mm shaft, 5.5mm head
Adjusts for 0.2mm clearance automatically.
3

Builds the 3D model

Correct clearances, wall thickness,
and mounting pattern all accounted for
in the geometry.
4

You get a .3mf

Download it, slice it, print it.
If something's off, just say what
to change and it rebuilds.

Not quite right? Just say so.

Parts rarely come out perfect on the first try. Just describe what to change and it rebuilds. No sketches, no constraint trees, none of that.

Add fillets to all outside edges, 1.5mm radius.

Done. Added 1.5mm fillets to all the outside edges. Here's your updated .3mf.

Make the walls 4mm instead of 3mm and add a slot for the ribbon cable on the left.

Walls are 4mm now. I added a 16x2mm slot for the ribbon cable on the left side, 5mm from the top.

Actually move that slot 2mm lower.

Moved it down. It's 7mm from the top edge now.
