Universal Roller for Belt Tensioner system. Has two styles for bearing holders - mounting holes inside/outside. Roller can be extended in slices to fit your seat belt guides.
Uses standard bearings and M3/M5 hardware. Stable design, been using mine for more than 6 months without issues.
At first I assembled with M5 screws on each side, worked for a month but then both rollers broke (printing vertically of course is not that strong). Since then switched to full length threaded M5 rod with nuts on each side - no issues whatsoever, holding up nicely.
