Bambulab P1S X1C AMS Spool Holder Roll Remix

To improve the almost perfect design from nagybirek, I redesigned the spool holder wheels (required 4x per spool holder).
I had some problems to fit filament spools of different manufacturers into the spool holder. 
 

I made following changes to the original design:

- Diameter of spool contact surface reduced slightly to 10,5mm: This helps to fit spools with slightly bigger diameter into the AMS spool holder

- Width of spool contact surface increased to max 6,1mm & chamfer added: This helps to fit spools with bigger side profile into the spool holder (see pictures as a reference)

Introduced usage of different spool thicknesses compared to the original design.
