I wanted a black LCD cover to match the rest of the parts I printed for my Bear Upgrade, and figured - if I was going to print a new one anyway - I might as well give it the Bear treatment!
The model was created in Fusion 360 using the original Prusa MK2s LCD cover as a design reference. This was made specifically for an MK2.5, so I can't say for sure if it will work on an MK3. I believe they use the same LCD module, so in theory it should work fine. Also note that I enlarged the hole for the selector knob to accomodate the 13mm round metal knob that came with my LCD module. The original printed knob from the Prusa kit still fits and easily covers the hole, but if you're using a different knob you may have to modify the hole size/position.
