Load Cell Spool Holder

I search some parts for a low friction spool holder, added a low cost load cell, some electronics and a OLED display. Wrote a small BASCOM program for an ATMEGA168.

The result : A spool holder with an integrated load cell for measuring the weight of the filament on the spool. From the weight we can calculate the lenght of the remaining filament on the spool.
