SERVO SG90 TO 6MM BOLT CONVERTER

thingiverse

I've made a budget-friendly adapter to transform the plastic piece of the SG90 servo into a standard 6mm hex bolt, allowing it to accommodate a 4mm threaded axis. All you need to do is print it and secure the bolt and nut with glue or colophony (also known as rosin or flux). I printed it using my Anycubic I3 Mega 3D printer with a 0.4 nozzle. You can find the settings in the picture. Check out this YouTube video for more details: https://www.youtube.com/watch?v=B5ekjmkBE9w. To attach the nut to the threaded bolt, I used colophony, similar to flux, which costs just $1 in China. Simply heat it with a soldering iron, pour it onto the threaded bolt, and screw it quickly into place. Once it cools down, it becomes rigid enough to withstand the force of this small servo motor. After that, you can connect it to an Arduino or Nodemcu V3 board and create whatever project comes to mind.
