Gridfinity ESP32/8266 Holder (22.86mm Pin Spacing)

NOTE: It has been brought to my attention that not all ESP32 use the standard 0.9" (22.86mm) pin spacing. I'm working on a wider solution for these wider ESPs, but for now I've updated the title and added this note to help handle any confusion.

I didn't love the other Gridfinity ESP32/ESP8266 holders I was finding as they all seemed to be designed for a specific make or model. So if you had short ones (D1 Mini) or long ones (NodeMCU), or ones with components on both sides of the PCB (D1 Mini), or ones with and without headers attached you had to use different holders.

All that is to say, I've tried to build a holder that works for most things. There are a few edge cases like the Seeed Studio ESP32C3 which is smaller than a penny which probably wont work with this design. But those are edge cases in my opinion.

Anyway, hope this is useful to some of you. And let me know if you have any models that don't work or want modifications.

P.S. I didn't include slots for magnets (as I never user them and they add to print time and complexity), but if enough people want a version with magnets I'll add that.
