Description
Update: Universal Spool Holder For Filament Rolls Up To 80Mm Wide. Https://Www.Thingiverse.Com/Thing:2486863 The Filament Scale And Usage Meter Is Based On Arduino Uno And Load Cell With Hx711. The Scale And Spool Roller Combination Is Able To Provide Continuous Measurement Of The Weight Of The Filament Spool, Thus Calculate The Estimated Length And The Filament Based On The Density Of The Filament. It Can Also Mark The Start Weight Then Track The Actual Change Of Spool Weight Before And During The Print And Display The Difference. It Can Also Measure The Actual Weight Of The Printed Object As A Regular Table Scale. Bill Of Material: Arduino Uno Or Clone X1 5Kg Weight Cell With Hx711 X 1 2004A 20X4 Lcd Display With I2C X1 12X12 Push Button Micro Switch With Cap X2 602Zz Bearing X4 M4X16 Machine Screw X2 M5X16 Machine Screw X2
