3D model description

Spool Holder:
A trio of parts that will allow you to suspend your spool on a 80x12.7x12.7mm load cell for processing remaining filament in an Arduino MCU with an OLED display and interface buttons.

This was designed to fit into the stock Ender 3 bracket in place of the hollow filament holder, and for the load cell to be attached to both bracket and spool with the appropriate M4/M5 hardware for the load cell.

I printed the bracket at 100% infill, as it will be supporting the entire weight of the system, but that may be overkill. You're welcome to experiment. The rest I printed at a lower, but still pretty high, infill. I tend to overbuild things, as you can probably tell from this design.

The spool holder is designed to take 4 10mmOD x 5mmID bearings for the spool to roll upon, and should press fit into place with little trouble. If they are too loose and threaten to fall off, a little dab of adhesive on the inner race should secure them in place.

Interface Panel:
I have recently completely redesigned the interface panel. The inside is now constructed with a proper perfboard installation, and the Nano, buzzer, HX711, and micro tac switches are soldered to the board, along with the requisite I2C pullup and button pulldown resistors.

This is a functional, but potentially not complete, version of the Filament Minder software. Instructions for use are on the Github readme.
