I bought my first 3D printer in April of 2020 during COVID. I never unboxed it until a couple months ago. I purchased some Dremel PLA and ABS spools to use with it. I have since purchased the Bambu Lab X1-C with AMS, and I wanted to use the Dremel spools with it, but the diameter is too small, so it doesn't fit the rollers in the AMS. I first created an adapter to work with the smaller cardboard and plastic spools, this one works with the slightly larger Dremel spools.

I recently purchased my 2nd printer, a Bambu Labs X1-C with AMS. I have some old Dremel spools that won't fit in the AMS as their diameter is too small. There were some other adapters, but either they were a tight fit or didn't work with both plastic and cardboard Dremel spools. This adapter works with all of my 179mm spools. I may upload an adapter that works with 180mm spools if I decide to print that version to test it.
