AMS Driven Rear Roller replacement

After fitting some “self-centering” rollers to my AMS, I discovered that if an odd-size spool has to sit to the left of the guide rail or is otherwise narrow, the spool is tilted over to one side and it wants to move across the rear roller. Unfortunately, I managed to break two of the original rollers getting the bearings off, so when I went to put them back in, I couldn't. Not wanting to spend the money to buy new rollers, I decided to make these simple replacements out of TPU. They print very easily in two halves, they don't use any shafts, the bearings slip on easily and have the dual purpose of holding the two pieces together (no glue necessary!). And I'm confident they won't wear out quickly. I made them slightly smaller than the originals to give a bit more room to the top cover and the TPU surface means the spool gets a better grip on the roller, so win-win! I suggest trying the 3mf profile and I strongly suggest printing these in TPU if you can, though they will print and work
