This is another one of my favorite Creality Ender 3 3D prints. Its a Useless Box easily available on Thingivers for free. It uses an Arduino Uno, servo, a toggle switch, and a 9V battery. I did not get into details on assembly and circuit component level but its fairly easy to put together.
Ender 3 Pro has been my very first 3D printer and to be honest, the print quality is amazing. After few Ultimate Cura slicer settings, I was able to get even better results. I highly recommend this printer as it is cheap and by far the best. If you liked the Video, give it a like and don't forget to hit the subscribe button.
