Great resource thank you.

Is this plane supposed to be the inside of the case wall or the outside (if so how thick was the case wall inteded to be?)

It's to the inside of the case wall:

Datum 0,0 is 0.4" from the board edge, so the distance from the board edge to the case wall is 0.083", or 2.1082mm

Hi, Thanks for this model...

If only I knew about this one before.

Is it safe to take this work, remove every unecessary object (like text, E-atx etc etc...) Minimize it and upload it with a mention to this file?

I mean Aibohphobia is not here anymore and I can't find any "Subtec" User to ask permission about...

I would like to upload it on my thread and website, with of course a link to this great ressources.
