About this 3D model
This is honestly the most functional thing I have on my printer. It actually stiffens the Z axis tremendously. You replace your Einsy door, which you only used once anyway, with a brace that connects the Z axis to the Y axis, so the left side of your printer is now rigid like the right. You keep the original Einsy base and dont have to disconnect any wires. Technically it is a remix since I borrowed the brace dimensions measurements from this more complex mod https://www.thingiverse.com/thing:3424832 after I printed it, but designed it from scratch using the stock Prusa door part in Fusion 360.
