Prime_E AngleMod Case

cover angle

Angled case design for the Prime_E keyboard. Includes two sets of files:

  • Unbroken case for large format printers
  • Logically split case for smaller print beds

Please note: the design is compatible with the Rev2 Prime_E PCB, I haven't tested it with the Rev1

Changes from the original case

I remade the whole thing from scratch around the Rev2 PCB but the main differences are :

  • 5° angle
  • smaller usb cutout and centered on the usb port
  • switch cutouts are simple squares instead of the "dog bones"
  • more clearance for stabilizers
  • tweaked the exterior lines to be parallel with the switches
  • on the split version, two screws are used to hold the top halves together

Assembly

Item Quantity Notes
M3x8 Screws 20 (+2 for the split version) I used socket heads, but other types might work
M3x5x4 brass inserts 20 (+2 for the split version) I strongly suggest getting the same type as thoses I linked. I find them easier to install and stronger than the ones that looks like a simple cylinder with vertical stripes at the ends
30x5x1.5mm rubber feets 4 You can of course get some with different dimesions, but they won't look as nice, because I put small recesses on the bottom for this size

When assembling the split version, be careful when installing the inserts holding the two halves together, they sit at an angle
