Remixed jecoffey's awesome design, made it a little thinner and a little shorter, removed the loop and put holes in the top for pullchain. Exterior case prints hole-down with a brim, no supports needed. Interior holder can print either way down, but if you print holes-down don't use a raft (learn from my mistakes). Minimal supports are needed (see photos). Don't print them at the same time, PETG is too stringy.
