Prusa i3 Hotbed Cable Strain Relief

thingiverse

I'm concerned about my Prusa i3 clone's stiff loom tube that holds the hotbed cable. I fear the connection will break when the bed moves. Required Components: 2 x M3x20 Socket Cap Screws (ISO 912) 2 x M3 Nuts 1 x 2mm Cable Tie I designed two versions of the loom tube fixation, one with the tube perpendicular to the hotbed and another at a 20-degree angle. First, place the lower section under your bed. Secure the loom with the cable tie but do not tighten it fully yet. Next, add the upper parts and secure the entire block by tightening the M3 screw. Finally, give the cable tie a firm pull to fixate the loom tube in place.
