This is a remix of user Brandon's Gravity Spool Holder Base, with 3 degrees of additional slope, in case you've got a lot of friction in your PTFE tubes or are otherwise in need of a little extra pull. The “feet' pictured on my base are the sticky foam feet included with the Prusa bases that came with the MMU2S. They help to muffle some of the “clunk” that occurs when using the Gravity Spool Holder. There are other great mods for this that totally eliminate the “clunk”, but I found these just weren't right for my situation.
