This is similar to other tools available but I wanted to create my own. It's in use daily.

Everything should print without supports

To complete you will need:

3 x Idlers

6 x V rollers

1 x 2040 V-slot extrusion

M5 bolts

GT2 belt

Weights (I use 608zz bearings)

I've included STEP files so you can customise to your liking
