PolyTerra AMS SPOOL adapter rim

100% functional and fitting adapter for cardboard POLYMAKER - PolyTerra spool filament. It is fully AMS compatible and can also be closed and secured. I thought I would download it and print it, I downloaded two models, one had thin walls and the layers of the PLA material cracked, the other one did not fit the holes that the creator modeled there. That's why I decided to draw it again so that the wall was strong enough, it didn't tear in layers. I also added a side reinforcement and this increased the contact area with the rollers, so it doesn't have a chance to slip. The diameter of the coil is 199 mm
