Update 16- april 2018
Finally (again) I have designed a rear panel and a mounting bracket. The bracket mounts to the M10 threaded rods with the help of 2 extra nuts and washers. Use parker screws to mount the rear directly in the plastic of the front. Or edit the freecad file and make the holes you need.
Finally I have made a closed case for my reprapworld keypad integrating a display. Now all it needs is a rear cover with a nice stand.
The reprapworld keypad features some easy buttons for moving the nozzle in x,y and z direction as well as a homing button.
If you like it you can get it at www.reprapworld.com.
Chilance and 3DAndy, thanks for the inspiration.
Designed in Freecad!
No support neccesary.
Brim is only neccesary for the case.
Flip the buttons before printing.
