I wanted a cover for my CFT1 to protect the screen, buttons and knobs when I put it in a pack. I wanted something that was easy to print, required no support and looked as good from the bottom as it does from the top. Print out all the parts, including two of the knob covers and use cyanoacrylate (super glue) for assembly. You will need four small round magnets, the ones I used were 8mmx2.5mm. The top is flat so you can use a range of sizes, just glue one on each corner.
