Prusa i3 Hotbed Cable Strain Relief by RostockMini4tw

Last crawled date: 3 years ago

On my Prusa i3 clone the loom tube that holds the cable for the hotbed is quite stiff. I was worried that the connection will brake when the bed is moving.
Needed parts:
2 x M3x20 Socket Cap Screws (ISO 912)
2 x M3 Nuts
1 x 2mm cable tie
I designed two version of the loom tube fixation, one where the tube is perpendicular to the hotbed (shown in the pictures) and one with an angle of 20 degree.
Place the lower part first below your bed and fixate the loom with the cable tie. Don't fully tighten the cable tie yet. Add the upper parts and fixate the complete block by tightening the M3 screw. Last tighten the cable tie to fixate the loom tube.
