3d printable design kitchen scale - operation and calibration

This kitchen scale can be printed on an ordinary 3d (FDM) printer. The project consists of 3D printed mechanics, electronics and software. Here you can see the software features of the scale. The Wiring diagrams,software and 3d print data can be downloaded for free:

Don't you feel that even there are insane cheap kitchen scales (ie Lidl, Aldi, AE,...) nothing pays the pleasure of building your own? Thanks for sharing; one more time.

That is true, there are surely cheaper solutions. I think the advantage for my own solution is the possibility to calibrate it very accurately. After calibration I found for 3KG an inaccuracy of about 0.2 g OK, for food recipes it is not that important, but the project can be used for any other purpose and weight, since the weight unit in use does not matter. And the quality is just dependeing on the repeating accuracy, because it can be calibrated. So I think the good thing is not the design of the scale, but the software I wrote for the arduino.
