Update: Revolutionize Your Workshop with the Universal Filament Roll Holder. https://www.thingiverse.com/thing:2486863 The innovative filament scale and usage meter is built around the Arduino UNO and load cell with HX711, providing seamless measurement of the weight of filament spools up to 80mm wide. The cutting-edge scale and spool roller combination enables continuous measurement of the weight of the filament spool, accurately calculating the estimated length and the amount of filament consumed based on the density of the material. It can also record the initial spool weight, tracking real-time changes before and during printing and displaying the difference. Furthermore, it functions as a regular table scale to measure the actual weight of printed objects.
