Filament Roll Ruler

Ever find yourself wondering how much filament is left on a roll before you print? Some rolls have markings, but not all do, and they may not be easy to read at a glance. This is a filament roll ruler that I designed that quickly clips on and off your rolls to give you an idea of how much filament is left. Currently only supports cardboard rolls accurately. Working on a version for plastic rolls like Bambu and Sunlu. Simply slide the ruler piece into the base and tighten it to your liking with the printed screw.Clip the base onto the roll and slide the ruler down until it touches the filament.Then glance at the pip holes and count them; each visible hole represents approximately 100g of remaining filament.This is a quick and useful print that uses less than 20g and prints in under an hour. Enjoy! For another useful print, see my Bed Handle V2!https://makerworld.com/en/models/838997#profileId-787075 Boost MeIf you love it, drop a boost!
