Nut-Bolt Pen Holder

thingiverse

A buddy asked for a bigger pencil holder, my mind wandered a bit and this is what he got. It neatly holds desk stuff on hand. The nut effortlessly turns up and down on the bolt. Another pal liked it but wanted it more as a toy, so I printed a second one at 50%. The Bolt walls get a little narrow with that version, but it still spins smoothly and is an intriguing little conversation starter.
