I designed this simple wallmount to get some sort of better arrangement of the KCM and all the cables on the back of the printer. There are 4 holes meant for threaded inserts (CNCKitchen M3 x 5.7) but double sided tape also does the trick on a flat surface. Just snap the KCM in Place and slide the retaining clip in from the top to keep it from falling off. 

Feel free to modify and improve the STEP files.
