I sized this for my Balance Plus broom, but you can open the attached .f3d file in Fusion and adjust the internal diameters to friction fit whatever size your broom is.
Buy 1" Teflon furniture sliders from Canadian Tire or Home Depot, remove the foam/adhesive insert the sliders come with, and then glue the Teflon shell directly to this part.
I printed mine in TPU to make it durable and help it friction-fit to my broom.
