Filament spool holder V.2

Updated version V.2 with longer pulleys and bearing spacers. This way the holder can accept different filament spools (from 40mm to 65mm wide) without adjusting the arms. You can use short M5 screws without the new washer525, but for a better stability I advise to put longer M5 screws (30-35mm) and split the bearings apart.

This is V.2 of the filament spool holder. Added arm in front of the spool. I made the change, because when the spool is almost empty (respectively light) it tends to jump over the front wheels.
With this version you have the option to use either lower wheels and a pulley for the upper ones or mount just the rear and upper wheels. I have tested it with empty spool (just 3 layers of filament) and it's no longer jump over.
As usual, please offset at least vertical holes (I used 0.07) for the threads. Otherwise you have to make the threads manually.
Supports might be needed only for the 625 pullies.
