We have in the lab a LOT of empty spools. Not wanting to throw anything away We decided to make a sculpture instead! Using the Prusament connect (https://www.printables.com/model/36779-prusament-connect)We made the shape but completely missing that the thing does in fact have wall mounts I created a new one. 

This design fits the inside of a spool and allows for a quick mount/de-mount from the wall. This was really important since the sculpture grew whenever a new set of connectors was done!

Use this mount if you just want a simple way to mount Prusament spools to a flat surface. Go!

Print a few rings and boggle at the annoying design that is circular and then not.
