Just stack in as many as fits nicely , I recommend white lithium grease in the slots for the bearings (the shorter tracks). Keeps it from rattling and holds the BBs while assembling. Its quite the puzzle. I'm printing my first PETG one right now, only part that doesnt work is the worm gear. The support structure won't come loose, it worked with PLAplus. Dual extruder machines can use petg for the support structure.
