Spool Roller

thingiverse

Decided I didn't like the original spool holders, so I made a roller that mounts on them. The roller is 49,5mm in diameter (because the spools I use are 50mm) and it's 70mm long. It's threaded with a left and a right hand thread (M10x1.5) and the screws are too, so that when it rolls it tightens both screws rather than unscrewing one side. Works like a charm on my printer :)
