Filament stand Prusa i3 MMU Version 2

thingiverse

I've upgraded this thing with four additional spool holders on the bottom part of the frame. This was made possible by raising the filament spool holders with distance pieces of 70mm. The Thingiverse files here only contain the upgrade to get from the original version https://www.thingiverse.com/thing:2787770 to this current one. This means: 1. Distance pieces for lifting all four upper spools by 70mm. 2. New filament guides that guide the filament from both the top and bottom. 3. All spool holder parts for the lower four spools. 4. An improved version of the Bolt, or Filament spool center rod. Additionally needed: - Ten T nuts M4 https://www.aliexpress.com/snapshot/0.html?spm=a2g0s.9042647.6.1.YQKrEu&orderId=505246412960296&productId=32706324351 for mounting the new bottom holders - Ten square M4 nuts for mounting the upper holders distance pieces again - Ten M4x16mm screws for mounting the upper holders distance pieces again - Four PTFE tubes, ø4 x 20mm, for the lower filament guiding. This current version also doesn't need the five-millimeter space pieces mentioned in the add-on section of the original version.
