I've been wanting to make this custom for some time, there was a notable challenge in simply FINDING the model online, I finally found a discord community that had several Sonic game models ripped that weren't on other sites like sketchfab or models resource. But once I got it I had Korey smooth it out and make it printable, then I modded the parts in tinkercad so I'd be able to stick joints in them. The joints for the legs come from a Mega Construx kit of the mecha from Destiny, the shoulders are a couple ball joints from a mega construx ekans, and the elbows are figma joints. Sadly I don't have the engineering know how to make it transform into a wheel, but hopefully some day an official toy of this thing will come out that CAN do that.
