Bearing adapter for direct drive (UM Original)

youmagine

When installing a direct drive on an Ultimaker Original, you typically don't have to reorganize new 8mm rods. This adapter shifts one bearing by 16mm, which is enough space for mounting Calum's direct drive setup including its more rigid and refined version on the opposite side. The adapter features a holder for the bearing, a round plug that fits into the original hole in the Ultimaker wall panel, and holders for M3 hex nuts used to secure the end caps. It's recommended to print this adapter on a 3D printer with high precision, such as a standard Ultimaker Original equipped with long and short belts that are neither too tight nor too loose. Printing it with the bearing hole facing downwards is advisable.
