Some love it, some hate it. But the 15th Doctors sonic screwdriver is BY FAR my most complex, time consuming build ever. Boasting around 40 resin 3d printed parts, this sonic was designed from scratch in CAD over the course of a year. Each part was sanded and painted. The final chrome layering process took a few days alone.
For tech, each sonic has Bluetooth phone controls, speaker and ability to answer phone calls, rfid cloner/writer, universal remote, and of course, Sonic Pay.
