I had the same exact thought. I have been using a lot of Overture PETG which comes on cardboard spools. I found some printable wheel attachments that help solve some issues. But occasionally I find that the spools get tangled when retracting.
Have you looked into the hydra mod for the ams? It seems like a lot of folks use it. I’m debating printing it myself or ordering a print from matter hackers.
