Filament Mount / Roller

This is a Top Mount Filament holder I designed. Printed in PLA with 80% infill for strength. Uses 8/32 screws and nuts. The nuts will slide perfectly inside top rail and will not spin when tightening screw. Mount is designed to fit the screen door roller kit B639 by Prime Line. Can be purchased at Home Depot. The screws used to screw the roller kit down are #6 sheet metal screws 3/8 long.
