Bearing Shield for 4x13x7mm Pulley (line retention for drawer/linear slide)
thingiverse
This part was designed to keep the cable (UHMWPE braided fishing line, in our case) in place on a pulley to drive a linear slide mechanism. The particular U-groove pulleys were sourced on Amazon. Because 3D printed parts relatively soft, to fasten the pulley to your mechanism I'd recommend using a pair of jam nuts to take more of the load while allowing the pulley bearing to rotate freely. The Solidworks (educational license) source file is included for your modifications.
