Filament scale mounting parts for use with the injection molded spool holder included with Prusa printers (I have an MK3S, not sure which exact models ship with it). This will replace the twist-in part.

Designed to work with the Filament Scale Enhanced plugin for Octoprint: https://plugins.octoprint.org/plugins/filament_scale/

The entire assembly should fit inside a standard filament roll, though it was designed specifically to work with Hatchbox spools.

PLA works fine for all parts, but using something tougher for the Mount would likely make it last longer.

Additional Hardware:

-4X M4 screws (most cheap load cells use M4, including the ones recommended by FSE)

-2X R4A-ZZ bearings

I also designed an enclosure for the standard HX711 ADC Module that typically ships with the load cells: https://www.printables.com/model/795496-hx711-adc-module-enclosure
