I have now printed beautiful finished items with TPU82A with no issues what so ever. No mods done to the filament tensioner
Print the spool mount holder out of PETG 0.28 mm layer height and a 10% infill.
Spool holder print out of PLA at 02.8mm layer height and 15% infill - Use supports for the bolt section.
I used the following 6003 bearings from Charlie to fit to the ends of the spool support - https://makerworld.com/en/models/445404?from=search#profileId-351852 (Special thanks to Charlie)
