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
- two M3 hex nuts
- additional material from Calum's direct drive or any other direct drive design
- recommended for position adjustment of the rod:, using a M3x25 or a M3x30 screw and a M3 hex nut.
