Polymax to MakerBot spool adapter

I love using Polymaker PolyMax PLA filament with my MakerBot Replicator 5th Generation printer. Unfortunately, the Polymaker spool is wider than the Makerbot filament spool, so it won't fit on the spindle of the filament compartment. This adapter lets you snap the Polymaker spool onto the Makerbot printer (with the compartment open).
