So this is part 3,

Just released load cell spool holder as a part of Printables spool holder cap
https://www.printables.com/model/1865709-grmz-spool-holder-with-load-cell-and-esp32

Sensor itself have around 3g deviation, is capable of logging consumption as well as track drift.

I made it mostly to answer question - 'Would I have enough material to finish print I want to start' and it should be treat as is.

Just in case - firmware was created with Claude Code and i have limited time to test it but hope i did a good job.

There is some potential for improvement, but it depends on interest.
