Improved hub for macegr Solder spool

I really liked this design but I was not quite happy with the hub screw being loose even with a nut. I added a m4 nut recess and made the flange 1mm thicker. I am very happy with the way it turned out so I figured I would share. Sorry no Openscad file

Qty2- hub.stl
Qty 2- M4x25 bolts (can be any head I used hex bc thats all I had.)
