Got me a large format 3D printer (called a CR-10 for those interested). Prints 12 by 12 by 15 inch area. I'm just printing the last 6-7 inches of the car (thoughtfully shared by 'Pixelpushing'.). Will splice to aluminum parts to make a complete car. Print expected to take 31 hours total. These thing print with a 'shoeshoe' around the part to make sure it sticks, I used a bunch of 'Frogtape' to make sure it sticks. (all the green stuff.)
