There are a million Raspberry Pi cases already on Thingiverse, but of course none that fit my Pi Zero + RedBear IoT pHAT.
I asked my son if he could design one for it and he can! :-)

He used a digital caliper to measure the sizes, used info from others online and designed a a case from scratch in Fusion 360.
After a test print for the optimal lid friction settings, he printed the case in glow in the dark PLA (nobrand AliExpress stuff). And the case fits perfectly.
The green LED from the Pi Zero lights up the case, the design in the lid looks great, leaving me to be the proud dad that I already was.
