We recently installed an Ender 3 V2 in our off-road camper and with space being at a premium, I tried to make it as compact as possible.

The X-axis adjustable tension mechanism stuck out much further than I would have liked, and would catch other wires and such. So I whipped up this quick pully holder that uses the same pulley and screw.

I assumed I'd have to find a way to tension the belt at the print head, but the first one fit perfectly, I've also included one that spaces the pulley out another 0.5mm if you need it tighter.
