If you're using your 3D printer a lot it's nice to keep your work surface free from junk. We like to keep our most used tools handy (glue stick and cutters) and so designed this tool holder that fits with the 3D UPfitters line of 3D printer enclosures.
This design is listed as a product just in case you want us to print one for you, but this design is available on Thingiverse for you to print yourself. It comes in two versions: plain and fancy. The first is easy to print with any material; the second has some cool wavy sides and will require support at least on the bottom. It's difficult to print well, though, so we provide both versions.
