This is a remix of the original openscad implementation for Arduino Nano -- https://www.printables.com/model/118444-parametric-breakout-board-sockets-esp8266-nodemcu-

This is a breakout board that I use for storing Pico boards, soldering, and straightening pins. It generally makes handling the Raspberry Pi Pico easier when it's not attached to a breadboard.

Materials and print settings used for this model:

0.4mm nozzle, eSun PETG with 0.15mm layer height, 3 perimeters 3 layers top & bottom and 15% infill.

I calibrated the extrusion width for the spool for 0.4mm nozzle by following this guide – https://guides.bear-lab.com/Guide/Extrusion+multiplier+and+filament+diameter/8

Consider using ABS if you are going to use this board as a soldering jig. Note, in that case you may need to adjust pinwidth parameter in openscad file to compensate for different rate of  shrinkage of ABS vs PETG.

If the first layer doesn't stick properly to the bed, clean the bed first, then reduce first layer speed in Print Settings → Speed → Modifiers → First Layer Speed to 10 - 15mm/s
