A chute that uses 28 10x2mm magnets or 14 10x4mm! I wanted a chute that I couldn't find anywhere! I had a lot of trouble with the first purge chute I printed getting full, this chute fixes that by allowing the use of a huge bin! I just sliced the model in the slicer so if you have a large printer you can print it as one piece, I just super glued the two pieces together!
