EIBOS Polyphemus knurled Roller

I made a knurled roller for the Polyphemus. I also included the Fusion archive so you can adjust the diameter in the parameters to your liking. Do not use PLA because it will warp under heating. PETG is too slick most of the time. I recommend ABS or ASA but could you do your own analysis? I printed mine vertically with a small brim on my X1C, and it came out fine. I also tried on the A1(yeah, yeah, I know it isn't supposed to work, but the part is so small it doesn't warp. Yay, my first post. I'm also considering making back rollers to keep spools centered where they don't walk left and right.
