And now, Federmann, tell us, what do you feel, when you take this heavy machine into your own hands ? Aren't this sharp corners of heatsink little bit painful ?🙂 But I know, you are using them at the first time...not all was forty five years ago for copying...
4 mm, Federmann, really ? Have you heard sometimes about so called small chain test? Or about test with false finger?

Upupa epops

Yes Federman, this is standard made case, which have sharp corners too, unfortunately...but yours is custom made... My own cases have rounded corners every time....

Upupa epops you saw a human finger as 4 millimeters thinner?
Yes Federman, ... My own cases have rounded corners every time....
Upupa Epops why I do not see rounded corners? : D

Ask men, Federmann, which have write this norm...norm tell, that this hole may be only 3 mm...
Upupa epops you are wrong, you have a lot to learn still. 😀
Probably, Federmann, 'cos you don't know to read...I was saying MY CASES, this one is not mine...
