This will keep your Speed Editor dust free and protected when sitting on your desktop, or if you want to toss it in a bag for travel. The tall version is a one piece print that's the height of the jog wheel. The thin version is a two piece assembly. The first piece is just thick enough to protect the keys. The taller knob cover attaches with M3x6 button head cap screws and M3 nuts. Because the knob cover is easily swapable, I made two versions with different styling. The smoother knob cover is slightly taller, to give a bit more clearance for the jog wheel.

Material for all prints is TPU. Print the trays with the flat side down on the printer bed. The trays just barely fit on a Prusa bed. The trays print with no supports. Print the knob covers with the visible side up. I used “painted on supports” to provide a support in the middle of the cover to keep it from drooping. The fasteners can be purchased from Amazon.
Because this is such a large print, you may need to tweak your print settings for good first layer adhesion. I found I needed to drop my first layer nozzle height by .020 mm to get good adhesion across the entire print. The tall cover (black) had peeling issues that messed up the surface finish, but was still able to print without crashing. For the thin cover (purple), I kept tweaking until I got a good part with a clean surface.
