Optical encoder slot wheel

Count wheel turns on a small robot

Press it onto the double-flat shaft of a yellow TT gear motor and let the teeth run through a slotted optical sensor: each tooth is one pulse, so a small robot can count wheel turns, drive set distances and keep two wheels at the same speed.

Questions

What size is the optical encoder slot wheel model?

The optical encoder slot wheel model measures 60 × 60 × 7 mm (width × depth × height). You can change every size in the free SO3D.xyz generator before you download it.

Does it need supports?

No. Prints flat as a plate, no supports.

How much filament does it use?

At most about 5.5 g of PLA (4.5 cm³ printed solid), roughly $0.11 of filament at $20 per kg. Normal infill uses less.

Can I change it?

Yes. Open it in the SO3D.xyz generator (free, in your browser), change the size, walls, dividers, holes, text or anything else, then download it as STL or 3MF for your slicer.
