Two years ago I bought a 10-pack of fine-tip sharpies, and wanted a way to hold and display them. The result was this nice little sharpie holder.

The make in the photos is about two years old and one of the first prints I did on my Ender 3 V2, which is why it looks so rough lol. I've since upgraded to a MK3S+. The site won't let me upload the original Ender 3 V2 gcode used to make the timelapse below, so I've included newly-sliced MK3S+ compatible gcode for completeness' sake.

This was also the second thing I ever designed with parametric CAD (back in November 2020), so if you poke around in OnShape be prepared to see some newbie mistakes!
