So one major challenge of this design is you need a large printer to print the spool holders. After lots of tweaking I finally got ALL the pieces to print on a Flashforge Finder 120x120x120 bed with lots and lots of supports. The red one I printed at a 45 degree and just barely squeezed it on to the build plate. On my second one, I was able to get ALL parts on the build plate and print at once. Total 17 hours, 20% infill, and three shells.
