Spool holder TPU

This is a spool holder for very soft TPU or TPE. You need an 608 ball bearing, if possible a decent one, makes the movement much smoother. I tried everything but always had issues with very soft TPU. With this spool holder it works like a charm. You just have to glue the two parts from plate one on the flat side together and put the bearing in. Then put the top part on the bottom part and the TPU spool on top. If you put the whole thing in an airtight enclosure it's even better, you just have to position the valve with the PTFE tube in the middle of the spool to almost reduce the friction to pretty much nothing. Just print the model with PLA it will hold up just fine.
