Ben tears apart a broken laser printer to see what parts he can salvage from it. He finds a variety of useful items from springs to opto-interrupters and muses about how the parts can be incorporated into future projects. A heap of ABS plastic is left in the wake of the teardown and gets Ben brainstorming ideas of how it could be turned into 3-D printer filament instead of going into the recycling bin. Ben ends up with a bunch of new parts!
