Maybe someone already has a drawing they can share?

This person @PJ_Glasso has a lot of experience on this topic. See:

Another Xiao Socket adapter Revision III

[_2] [Small_Moment] [Xiao_socket_octo_small] A truly solderless socket for testing Castellated PCB micro controllers like the SeeedStudio Xiao Nrf52840, my First crack was fashioned after Rizo’s ESP32 Sockets, Very cool. No pins to bend with this one, just print and add a few pieces of the hardware pin sets. You can add the pogos as I did for connection to the debug pins on the dev board. NO more soldering and unsoldering the PCB’s until final assembly. ;-p files are up on Thingiverse enjoy…
