Printed this in TPU, glued three 12.7mmx1.5mm magnets into the pockets and applied a dab of grease to the ID where it rubs the spindle. I printed at 100% scale and it was snug but grease slid it right on. You may need to adjust scaling to 100.5% or even 101% depending on what TPU you use. I used Bambu AMS compatible TPU (Black)
