I have made some small updates.
Moving the screws to the bottom is a bit more complex than expected and is still on the todo list.
It is ofcourse a matter of preference. Having the screws on top is more convinient for assembly.
In order to compensate somewhat the “temperature leaking” I have added two new elements with a 20mm and 30mm extension for the SH3x.
I share now the folder instead of the files so that updating is more convinient.
BTW what works nicely is the concept of the replacable sides. I can now swap out the sides without the need to reprint the whole case.
