We at 3DKToys (3DKitbash) developed SkullBot to say thanks to the communities of the various 3D printer websites for letting us know that some of our items had been placed on EBay without permission. Your attention and care for how IP is handled within and around the 3D printing communities is greatly appreciated by 3DK, and we wanted to make something fun for everyone to show our thanks. You all really do help us stay afloat. Thank you all. ~ Natalie and Quincy - - - - If you like SkullBot and are interested in the rest of the QuinSaga line, please visit 3DKToys.com.
