Weight with the ability to measure volume and size

The customer provided a steel body of weights with a built-in tensor and a set of components on which weights should be built.The components were:
Arduino MEGA 2560 Mini
Laser Distance Sensors
Tensor module with the TTL-232 - HX-750 interface (analogue HX-711 with the possibility of connection by TTL-232).Display from the Chinese company HUNDA H480x272 with an I2C interface.The tasks were to make the accurate measurement of the weight and size of the object, make the possibility of weight calibration, select the measurement units of size, volume and weight, add the transmission of data via Bluetooth, as well as sound indication.Since the components were purchased in China, this brought a small problemmy to work with sensors,so how there was no exhaustive description how to work with them.In the half of the performance the customer came to the conclusion that in the future it will need a WI-FI, so it was decided to switch to the ESP32 platform Wemos lolin.The code was adapted under ESP, the display library was re-written.The body,holders and many other details were printed on the 3D printer.The whole system is created on the model plate, so how this is the first sample and it is more for the production and discovery of the gods.The following versions will be:
Added support for Wi-Fi and data sending to the server.The individual printed fee is developed which will contain all the necessary interfaces and will be much less present, which will undoubtedly affect the quality of the product itself and its recognition by the buyers.The project is 100% commercial, on request I can send the video work of the device.
