PROBLEM TO SOLVE:
Plastic recycling is an obviously wonderful idea, and using the plastic immediately as a filament for 3D printing is an even better idea! However up to this point affordable recycling filament systems have been notoriously unreliable.
I believe by focusing on one specific item, like plastic bottle caps, it is possible to make a reliable all-in-one plastic recycler/filament extruder. This makes the crushing process more predictable, and the extruding process more reliable becasue there is less variation in the plastic. So meet the BitsBox, the all-in-one solution to take common plastic bottle caps, grind them down into little bits, and extrude them into usable 3D printing filament
