A strain relief for the heated bed is crucial! A failed thermistor wire can lead to thermal runaway which may or may not be handled by your firmware, and worst of all, if you have an AC heated bed like I do, the danger is even bigger if the wires or solder joints break.

So I designed this very simple and light strain relief, it has 3x 2mm cable tie points and is very secure.

My bed is modified so I'm not sure if the stock screws are long enough to accomodate the thickness of the part but Im pretty sure it will be fine. Let me know if there are problems.

I have included the 3MF, IGES, STEP and STL files so you are free to modify as you wish.

Printed in PETG with some supports, but any material should be fine. That's all, have fun :]
