thingiverse
This is a plug and play belted gear box with 3.5:1 gear ratio (when using a 16t pulley). I'm using it on my Bear extruder with an LDO 0.9 Slim Power stepper. Very inspired by https://www.thingiverse.com/thing:3553286 and https://www.thingiverse.com/thing:2845416 Print with PETG without supports, vertically (it should look like an arrow pointing up on the plate). Use at least 3 perimeters and 12% gyroid infill. Required hardware: 3x m3 20-25mm screws + washers 1x gt2 140mm closed belt 1x 16t pulley 2x 105zz bearings 1x ~40mm x 5mm shaft
