Hi there,
SO, It’s inspired by the ESP8266 and by the Italian guy originally 
It’s up on thingeverse and on here at the end of the posts, The STL
s’ and the FreeCad files. There are a couple way to put them together once you print them. some have the pogo’s and some don’t. You can use header pins or just cut and form some old resistor ends, (original-post) Just search “Xiao Socket” you get all of it
