Turntable Tonearm Tracking Force Scale

Things have gotten old-timey during this lockdown. Sourdough, marbles, now records. I dug out the old records and turntable and realized that I don't (and never had) a way to measure the tonearm tracking force. I was just eyeballing (earballing?) it. Turns out I was tracking WAY to light, I always wondered why other people's records sounded so much better than mine and the stylus bounced every time someone sneezed.

Enter this simple balance. This is not scientific, I'm not even sure how accurate it is really. I don't have a scale accurate enough to measure fractions of grams. If I did, I would use it to calibrate my turntable! The weights do balance each other though.

Cura tells me that each 1.0g "weight" uses one gram of filament when printed at 30% infill with 2 perimeters all over. The calculation here is that PLA is 1.24 grams/square cm. With a filament diameter of 1.75mm, that works out to be 0.34m of filament per weight. This also relies on the calibration of you
