This is a remix of the original: https://makerworld.com/en/models/46934#profileId-48732

I modified it a little bit to have a filament guide for the spool that is on the folable bracket. On the oposite side of the filament guide the is a hole with thread in it so you don's need a PC4 pneumatic coupling, Just twist in the PTFE tube and it will stay in there. From the guide you can put the PTFE tube that comes from the Y splitter (if you dont have one, look for Y splitter, there are enough to find on maker world).
