MK3 Zep Spool Holder, low profile

This was inspired by MartinMajewski's spool holder (https://www.thingiverse.com/thing:1832235). But I had a limited vertical, and needed it to be a bit lower.

Changes from his design:

• 1.5" lower vertical
• No need for zero top/bottom layers to get honeycomb effect
• Not really multi-color friendly, as it prints the shafts and spacers as part of the arms.
• Chamfered edges to hide elephant's foot
• Smoother edges.

Uses the same 608ZZ bearings.

Print one of each arm, four rollers and four nuts.

MK3_Zep_SpoolHolder_Sheet is all the parts, ready to slice.

I printed the parts with a 0.8mm nozzle at 0.333 layers, and it's plenty strong, and was a 5.5 hour print.
