Original design, printed without supports. Was ugly at some points, but it was still useable.
One error, when removing the supports from inside the now removed recessed holes for the screw heads, My drill went straight through and created a hole that was too large for the head. I had to use a 15mm screw and a washer to secure that point together. Also had some issues with the fit of the other screw holes that were addressed in the updated design.
