MMU3 Spool Holder spacer (60 mm, 70 mm, 120 mm widths)

When building the MMU3, the spool holders use some foam pads that allow the roller width to be adjusted but maintain position. The foam pads came off as soon as I tried to adjust the width. I saw this design by @EngineerDude that I used for awhile, but I wanted to make my own similar design that would fit the 70mm Prusament rolls I have.

Update: Added 120 mm version that fits a 2 kg Prusament spool.

Design goals:

• Hold the rollers evenly spaced at 60 mm or 70 mm (and now 120 mm).
• Minimize the amount of material needed to print.
• Print in the default orientation as modeled.
• Mark the parts with the dimension
