Skywatcher EQ5 / EQ6 Counterweight Thumbscrew

The typical Skywatcher thumbscrews used to tighten the counterweights are very easy to break by dropping or tool use. I've rarely seen a decent used mount with these intact.

I've built these to replace my own, a bit oversize - i found the original ones too small for my liking. Please note they go a bit over the counterweight edge on one side.

They fit snugly on the grooved, 9.5 mm wide head of the factory M8 bolts. Gently hammer them in after applying a drop of epoxy.

LE 19.09: The ones originally printed in PLA @ 15% infill gave up after some time, so I reprinted in PETG, with 40% infill - way sturdier. I now reccommend bumping up the infill on the PLA version or using PETG.
