Heatbed Cable Holder for Prusa-like Routing

I made this cable holder to be able to route the cable of the heatbed like at the original Prusa i3 mk2 and mk3. Here the connection of the heatbed is at the left corner, this makes it more easyly possible to route the cable backwards to the elecronics box.
I did not include a spring for the heatbed because I have a level sensor and don't need to level the bed manually.
Use 100% Infill and Supports. Also you need a temperature stable filament like PETG, PLA will not work due to the hot heatbed
