Spool Holder - MK "+ upgrade set"

Base Design is fix for 70mm wide spool + EDIT: upgrade set = width adjustment from 45mm to 80mm

After printing use glue for P1+P2 to assembly bearings between them. P3 assembly with screws. You can also use furniture stickers on the bottom - not required

Additional parts:

4x cylinder head screws M5x12mm

4x selflocking nuts (with plastic insert) M5

4x ball bearings 28(outside diameter)x12(inside diameter)x8(width)mm

EDIT 19.02.2023 

If you have already printed the base design (with fix 70mm width) and want to be able to adjust the width of the stand - just print out the "Upgrade set" and install according to the photos.

Additional assembly parts for upgrade I used from spare parts from Prusa:

3x nut M3nN (with plastic insert)

2x screw M3x12b (with tapered/conical head

1x screw M3x10 (with cylindrical head)

For width adjustment (from 45mm to 80mm).
