This is a pastamatic shim I made for the 200g Amolen sample rolls I had laying around. It works on any of the 200g rolls with a similar middle. I've used it on a few different ones including cardboard ones and it works great. I have been able to get even rerolls out of this and I've used it about 12 times with no issues.

I used Voxel PLA Pro Orange, I HIGHLY recommend their filaments. There rolls are designed for AMS and they are my favorit PLA and PETG filaments. HIgh Qualtiy and cheap, don't sleep on em!
