A very cheap, simple and effective belt tensioner for the belt of the Y axis of your prusa. Thanks to it, you no longer have to dismantle the whole bed to tight your belt.

Simple, functional and easy to assemble. What more can one want?

I wonder if it would be better inverted - ie the bearing pressing on the flat side of the belt?

Nop, it's still working ;)
