Download the two parts from this thing and only Rewinder_arm from Auto-rewind spool holder (for MMU).
Both the bearing insert and arm mount should be placed on the bed with the 8mm bearing post facing upwards.
Supports are required for the arm mount to print correctly. A support enforcer has been included for PrusaSlicer users.
You will also need the following parts from Multiple Mechanism Auto-Rewind Spool Holder:
- bearing insert
Plate these components as described in the source thing.
The components below were sourced as follows:
- gray parts are from my rewinder
- blue parts are from this page
- the gold part is from Martin's page
Assemble the cap, shaft, and nut as directed with one exception. The bearing insert from this page must be used in the cap's bearing. Use the normal insert in the shaft's bearing.
Insert the arm mount into the track's channel at the top of the stand.
Finally, install the arm's pivot bearing onto the mount's post.
