When realising a direct drive for an Ultimaker Original, you usually don't get around to organise new 8mm rods.<br>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.<br>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.<br>Print it with the bearing hole to the bottom.
