The pisound looks like a very interesting and worthwhile project!I would like a little more information about the case that can be 3D printed for the pisound.
We are looking at some options to produce "Google Cardboard"-style case. Bulk 3D printing isn't the best way to go and at this point we aren't able to start messing around with custom plastic moulding. Hope that won't be an issue in the foreseeable future.
Yes, the case is designed to fit both pisound and Pi.
The standard heat sinks (as in the picture below) fit perfectly as pisound "sits" higher than standard HATs - plenty of room there. We will update our documentation page with exact measurements later on.
Thanks for your reply, Pranciskus.
This is good news on all items.
