Filament Scale

This thing contains the STL files for a full featured filament scale with the following features:
• Accurate measurement of weight up to 5 kg with units selection of grams (g), kilograms (kg), ounces (oz), or pounds (lb).
• Accurate measure of filament length based on spool weight and filament density. Length units are selectable as millimeters (mm), centimeters (cm), meters (m), inches (in), feet (ft), or yards (yd).
• Extensive user interface using a color 1.8” TFT display and rotary encoder.
• Menu driven option settings.
• Displays environmental data of temperature and humidity with selectable Fahrenheit/Celsius selection.
• Database of up to 15 spools with associated ID string, empty spool weight, filament color, filament type, filament density, and filament diameter.
• Database of default filament densities with 12 built-in default densities, and 3 user definable densities.
• WiFi compatible, with built-in web page.
• Non-volatile sto
