I used a few models from @VincentGroenhuis to make the auto rewinder. The issue I had was that I want to use the PolyMaker Drybox system for my spools. This is a simple adapter that allows you to install the Auto Rewind Spool Holder in the DryBox.
You need to take the bearings and rods out of the bottom.
With the PolyBox you need to use the 85mm shaft.
The fit is tight on the D Shaft. Do not push it all the way through. A small drop of superglue will be a big help!
