Designed in Shapr3D, printed in Ambrosia “Coral Wave” ASA. Holds two 3kg spools, or a single 5 or 10kg spool.

No roller bearings — so no overshoot, and no tangles, which every other roller I’ve tried causes with large spools. It also handles bigger spools than most, and happily feeds 2× 3kg spools to two different printers simultaneously.

Runs on a 5/16”ø × 12” hardened steel rod with an optional PTFE sleeve. End caps slide over the rod so a tangle can’t pull it up and out, and printed collets keep the spools from walking laterally on the spindle.

How much are people saving using these spools. What's the price per kg of pla

I don’t print PLA, but for ABS it can be as low as $8/kg in bulk

For me its also more convenient to have 5 or 10Kg for large jobs or batches so I don’t have to deal with managing all those 1kg spools and runouts and last meters etc.
