Prusa i3 heated bed cable strain relief

thingiverse

This is a straightforward strain relief for heated bed wiring on Prusa i3 style printers. To mount this particular design, you'll need to drill two 3mm holes through the aluminum bed, so proceed only if you're willing to modify your print bed. I suggest countersinking the drilled hole and using Phillips head machine screws to attach, especially if you have auto leveling installed - you don't want your head hitting hex heads during printing. You can see in my picture that I'm currently attaching it with hex head screws as I'm out of countersink heads, which limits the print area to the front of the bed so the head doesn't impact the screw heads. Other than that, it's working perfectly. Print Settings Printer: Prusa i3 Rafts: No Supports: No Resolution: 0.2 Infill: 20
