An external foldable spool holder to use with the BaBo drawer. Since the AMS and the drawer close the gap, an AMS adaptor could not be used. So I remixed a design and added a few relevant designs together, so there is no need to search any further.

I made a few modifications, so some common screws can be used. The screws for the foldable part are inserted from both sides and the gap has been narrowed so the screws lock, while still being able to move the holder freely with minimal effort, but with slight friction.

The Y-splitter and the guidance device hold the 4mm PTFE tube tightly, so no need for any special materials there.

Screws needed:

• 2x bolt M4x20
• 2x bolt M3x6
• 2x nut M3

I used Bambulab PLA tough for printing. The Y-splitter was printed much earlier in ABS though.
