Spool Bushings
thingiverse
Currently, bushings are available for 32mm, 39mm, and 51mm spools from brands like 3D Printer Supplies (Amazon), OnlinFilament (Amazon), UltiMachine, and 3D Ink. These bushings fit the standard smooth rod used in a Prusa (8mm). To install, attach two bushings to your spool, insert an 8mm smooth rod, and secure it to your spool-holding mechanism. If needed, request another size or report if an existing size fits an unlisted spool.
