Small printed part that together with PTFE tubes, reduces the friction of a cardboard spool that is inside a USS Drybox while it's laying flat.
Although the Drybox is best placed vertically, there will be some setups where stacking the Drybox horizontally could be useful, and in that case, some cardboard spools do not slide properly, and if printing TPU, it is even more critical.
You will need x3 4mm OD PTFE tubes of 68mm of length. It is a bit tricky to get them in (you have to bend the PTFE for it to go in), but once they go in, they do not come out on their own.
