Angled USB Wall Mount (Cables or Thumb Drives) V.1
Based on this thing by me5647, "USB thing holder with center hole for magnet", https://www.thingiverse.com/thing:847379
I wanted all of the slots to be angled up and straight. I only screwed in the top left and bottom right and it seems pretty sturdy.
V1 slightly looser, 8 slot version.
V2.01 Slightly thicker base, slightly tighter slots. 4 slot version with two screw holes.
