Project Stand with Load Cell

Arduino Weighing Station (Load Cell, HX711, LCD 1602) / Arduino Scale Prototyping Station

Project Description

Say goodbye to tangled wires and scattered components on your desk! This project is an "All-in-One" prototyping station specifically designed to create a digital scale or a force measurement system.

The base combines all fundamental components for this type of project into a single compact and tidy layout. The design includes dedicated and custom-made housings for:

• 1x Arduino UNO Rev3
• 1x Mini Breadboard (for quick connections)
• 1x HX711 Amplifier Module
• 1x Load Cell (with its circular top weighing plate)
• 1x LCD 1602 I2C Screen (fixed on the tiltable front stand, to always ensure a perfect reading angle)

It is the ultimate educational and hobby tool for anyone wanting to experiment with weight measurement, keeping their setup clean, portable, and professional.

3D Printing and Assembly Tips

To ensure the scale is accurate, the load cell's support base must not flex. For this reason, structural print settings are very important:

• Material: PLA or PETG work great. PETG offers slightly more flexibility, but PLA is usually stiffer, which is an advantage for the load cell base.
• Walls and Infill (Crucial): It is strongly recommended to set at least 2 perimeters (wall loops) and a 15% infill (Grid or Crosshatch). A solid structure will prevent the load cell arm from flexing the plastic base under stress, falsifying weight readings.
• Supports: Enabled only for suspended parts (such as the screen joint and the raised housing for the load cell).
• Required Hardware: Prepare M4 or M5 screws (depending on your load cell) to fix the aluminum bar to the base and the circular plate, plus small M3 screws to secure the Arduino, the two parts of the LCD screen case, and an M5x60 screw for the display hinge.
