Hello,
I'm in the process of creating a 3D printed case for a project and wondered if a web page reported the boards physical sizes.
There is one but it seems it's not up to date with post-3.6 teensys :

I will get my caliper out and measure the few dimensions I need, but it would be nice to add the newer boards there it may be helpfull for those that don't have purchased their target board yet.
