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.
After my belt guides broke down I extended the design to mount directly on the seat. It needed an additional distancing base for proper positioning. Still holds up pretty nicely, works very well and is quite stable. It is mounted currently on Bride Low Max II seat but should be straightforward adapting it to any seat.
