Behold! A Remaining Filament Indicator which doesn'trequire you to open the AMS or Storage Container to measure how much is left - just take a glance inside!
Low Temperature (PLA) and High Temperature (PETG) profiles available since these will go in the dryer with the filament when needed
It is paper thin so..
It installs easily with a new spool of filament
Still allows use of any existing filament clips you may use on your spools
Does not interfere with RFID reading on BBL Filament
AND uses only 12g of filament!
Note: because its thin, be sure to let it cool on the build plate before removing to prevent warping (not that it matters much anyways because it is sandwiched with the filament.. but might as well keep it flat)
