Hotbed spacer for Prusa i3 (+ wire clamp)

thingiverse

I created this simple spacer to replace the default springs that came with my printer. They were no longer needed after implementing auto-leveling and decoupling the x axis from the z one - eliminating any possibility of breaking the glass. It's better to use (nylon) self-locking nuts so they don't become loose over time. I designed different versions depending on the height you want to leave between the bed frame and the hotbed, mostly based on the insulation system used. They are designed for a 10mm methacrylate frame, but the .scad file is available for everyone to adjust any parameter as needed. UPDATE 08-05-2020: I added a wire clamp version as a strain relief for the hot bed wires. It uses 2 small zipties. I made an 8mm version. Unfortunately, I accidentally lost the source code, so if anyone needs it I can redo it.
