Prusa I3 MK2 x-idler

thingiverse

Having had my x-belt to tighten I noticed that the brace got cracked because the idler screw was to tight. I already have been looking for some x-end idler with which the belt could be tightened I found none which would fit my needs. The one I made is as near to the original design as could be and quite sturdy. Beware, you need a well dialed in printer, the tolerances are small which is intended. For me cleaning the supports was enough, some sanding still might be neccessary. You need two M3 square nuts and two M3x18 or similar. Printed in 0,2mm, 3 shells and 35% infill proofed to be quite sturdy. Made with PETG from these guys https://www.3dpsp.de/ as all my other printer parts. No drooping or degrading at all.... This stuff turned out to be quite fine to process. It is quite sturdy, no problems with adhesion at all. And really nice and brilliant colours for a reasonable price.
