using the standard sv06 bracket spool holder , remove the spool post and put in the adapter so to be able to add the rewinder model , works pretty good .

I used a bit of 8mm threaded bar and a couple of nuts for the axle
built the standard auto rewind round modular
flipped the bracket to pull the filament from the right side of the spool as the springs in the rewind module are set for one direction unless you mirror all the springs.
