Overhead extension cord pulley
by destos, published
Built this pulley for the fab lab, as the extension cord drops weren't exactly where I wanted them…
It has 2 DOF so forces affecting on the main truss aren't great enough to snap the 3D printed parts.
Supports cables up to slightly larger than half and inch.
There is one large printable bearing
print-_head.stl that would be best to print in another plastic to prevent wear between the parts.
( I may try to merge those two interfacing parts into one part with a ball bearing design, in the future. )
