Hercules Guitar Stand Yoke Extension

This is for adding extra guitars to the Hercules guitar racks (GS525B and GS523B).

Tried to make it look close to the original, and fits snug enough that it stays in place.

I found (for me) the best way to print was to stand it straight up, like the letter "U", with tree support enabled. I used the Standard setting on Cura, set the wall thickness to 4 (from default 2) and 20% cubin infill, and a brim. Speed set to 60.

Takes about 3h to print.

NOTE: In the winter it was very very snug, but in summer a bit loose. Plastic and metal shrink/expand at different rates. May need to print 1-2% smaller if summer, or like I did, when summer came and got loose I wrapped 1 layer of black electrical tape around the metal pipe and that was enough to make it tight again. May be why the originals are a hard rubber... maybe use flexible filament?
