Print 30 clips to assemble 12 CDs or DVDs into a dodecahedron.(You can take a chance and skip step 1 and go straight to step 2. I printed the clips on a MakerBot Replicator 2 with 2 shells, 10% infill and a raft. Oddly one of the slots for each clip ended up a bit wider than the other slot even though the slots are the same width in the .stl file, but the clips still worked fine.) Print 30 clips using the "30 dodecahedron disk clips.stl" file. You can optionally print the dodecahedron clip placement template PDF to help properly position the clips on the disks. Assemble the disks one at a time until you have a dodecahedron.
