Christmas is here and I have more to PLAy with 
2.3Kg isn’t going to fit my cake box so I need to respool. An ideal time to measure the empty spoil weight, thickness, length and weight of the filament. Anyone seen any printable designs for a length meter? I’ll build both a length meter and load cell and see how well they both operate.
