Designed to fit the hole spacing for a Craftbot 3 machine. This gives you a "quick draw" for snipping your filament. The original screws for the Plexiglas window can be re-used. Just be sure to not loose the nuts on the back side. I have the right side spool holder at the 2nd screw position from the front ant the filament encoder at the first hole and it still fits A-ok. It's sized for a Menards branded 9-1/4" long scissors. May be good for similar models.

PLA or ABS shouldn't matter. Supports are only needed at the 3 retention tabs.
