Ender 3 Linear Rail Belt Tensioner
thingiverse
A mod for bobblejot's linear rail that allows you to tension the belt. Uses the same idlers as his with the same heat inserts (so no new materials if you're already using that). The screw and knob you can grab from Cornely_Cool's here: https://www.thingiverse.com/thing:3097972, you need one of the GT2's if you are using the BOM from the linear rail conversion (I use the M3). July 2022- Updated the stl with a version scaled to the correct size.
