Undermount desk side holder

thingiverse

Needed a good headphone holder so designed this one. And then made another one to hold my blue tape for my little Printrbot. Uses countersunk #6 screws from the underside of the desk, with the arc designed to clear any tabletop bigger than half inch thick. Prints with no support material without issue. I hit the raised letters with a quick coat of white paint to pop them out. The white letters on black material sorta feel like an old-timey radio microphone label.
