Simple clip-in holder for ATMega32 "Arduino Pro Mini" modules available cheaply online
Simple clip-in holder for "Arduino Pro Mini" modules. These are ATMega32 based boards similar to the Arduino Mini. They don't have USB hardware so are very cheap (<$5) and useful for small projects.
This prints reliably in PLA and ABS for me and the board will not fall out with vibration etc. As the walls are thin anyway, printing as solid (100% infill) when generating Gcode helps make them really tough.
