The Ruiz Brothers made this real nice case for the iPad Pro 11″. I have been using one on mine since I got it. But it was missing the cutouts for speakers and microphones. I was able to find the Apple Accessory Design Guidelines and get the dimensions and placement of these items.
I got this game called Point-Blank a while ago at Goodwill. It was missing two green pieces though. So I drew up the part in Autodesk Fusion 360 and printed out replacements on my Lulzbot Taz 5.

I designed the case for a Raspberry Pi Zero in Fusion 360. Design inspiration was from a previous Adafruit designed Raspberry Pi Face case for the B+ model. Noe Ruiz helped with showing me some design changes that could be made to improve on my original sketch. I also used the snap fit design shown on a Layer by Layer video to make the case so it requires no hardware to assemble.

This is the upgrades I have done to my Lulzbot Taz 4 and the enclosure I built for it.
