I used the following materials:
-M8 or M10 bolt 140-160mm length
-M8 or M10 nuts 2 x
-2x 22 x 8 or 30 x 10 bearings
-2 of each suitable files
The author remixed this model.
I tried to use the original hubs for the unwinder, I had a spool that was to wide for my ams, so i needed to rewind it on another spool. The wide spool was also to wide for the undwinder construction which made it clamped. the motor was not strong enough to run it properly. So i made an other axle that made it possible for wide spools to run properly.
