Bearing adapter for direct drive (UM Original)
Calum's design for a direct drive for the Ultimaker Original requires new rods. This adapter piece relocates one bearing by 16mm, enough for coupling the motor on the opposite side.3D printer parts and enhancements

When realising a direct drive for an Ultimaker Original, you usually don't get around to organise new 8mm rods.
This adapter relocates one bearing by 16mm. This is enough for mounting Calum's direct drive setup including the more rigid refined version on the opposite side. The adapter consists of a holding for the bearing, a round plug which goes into the original hole in the Ultimaker wall panel and holdings for the M3 hex nuts which are used for fixing the end caps.
It's recommended to print it on a 3D printer with high precision which includes a standard Ultimaker Original with long and short belts not too tight and not to loose.
Print it with the bearing hole to the bottom.
Materials and methods
- bearing 688 from Ultimaker Original
