3d printing jewelry at home can be a lot of fun, but most home 3d printers will only print in various plastics. There are plenty of commercial services available that will print in metal or other fancy filaments, but they can be expensive. This guide details one method of designing and printing your jewelry on your home printer, then making a silicone mold and casting the part in pewter. You can reuse the mold over and over, enabling you to make multiple metal parts for much less money than buying one from a 3d printing service.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
