This replaces the default filament guide that comes with the Makergear M2 printer. My filament was kinking and stopping the printer because of all the sideways pull, and this solves that problem. This also helps if you are using FluidDoc's smaller M2 Spool holder (Thing 31305) or if you have one of the wider-profile spools like the JET spools sold on Amazon.

The five guide holes will need bridging, so make sure your bridging settings are good to go. The bolt holes on the bottom are chamfered at 45 degrees, so they will not need any support.
