If you have a 3D Printer, you can build your own Marty!
You'll also need some electronics components to complete your Marty, we'd recommend our Control Board, Rick, 4 K-Power DMM016 Servos and 5 HobbyKing HK15178 Servos, a battery plus Charger, and optionally a Raspberry Pi and Camera.
Timings, layer heights and infill percentages are our recommendations based on printing with a BCN3D Sigma, Ultimaker 2 and Prusa i3.
The parts from our previous v0.1 release are still available, you'll find a link to them at the bottom of this page.
