Heatbed Strain Relief

This is my designed heatbed strain relief system, it does take away part of the printable area but i have never had it effect my printable are in practice as I have always been able to orient away from it. I used an M3 X 20 screw and locking nut but other lengths will definelty work too. I recommend printing in a high-temp material that is extra strong so that it doesnt deform.
