This time I ordered two types of circuit boards and four types of cases.
Both types of circuit boards were made without any particular problems and with the usual precision. I am satisfied.
This is my second time ordering a 3D printed case.
I knew from the start that the corners would be rounded.
It was fine for showing to my boss at work, but if anyone else places an order, I will warn them that the corners will be rounded and that the precision of parts less than 1mm is not very good. Nevertheless, the precision is sufficient for this low-cost prototype. I am also satisfied with the case.
