I have seen several of these online but they don't fit my MK3S or they are really flimsy. I redesigned the idea to make it solid and fit the printer WITH THE ORIGINAL BOLTS INTACT. The prusa original cover ignores the bottom of the bed and the bolts. All the low profile versions I have seen either do the same and become really flimsy, or they make you solder the connections or modify the bed. I just wanted an easy Bolt-On replacement to the original. It is a little bigger than others, but it puts the connections all inside and clamps tightly to the bed to transfer all the stress off the wires to the physical connections.
You can easily remove your old cover and put this on in 15 minutes with no modifications to the printer. You use the same nuts, but you will need longer M3*20 cap screws to fit the taller design.
