Filament Odometer FlashForge Finder

This is an odometer and spool holder combination for the Flashforge Finder, Obviously you could make it for any printer but the spool holder it dovetails into is for the Finder. It measures the amount of filament to the nearest Centimeter. I am using it to keep track of how much i have used from a spool so I know how much is left on one. The odometer is working flawlessly

it Uses TPU for the drive wheel and idler, and 2 bearings from McMaster Carr Part # 60355K501 the shafts are all 1/8 brass (Brazing Rod) Included is the .rsdoc file for tinkering with

Everything is printed on the Finder
(you have to place some things very carefully, but i promise it will fit)
