@AGHRMatt posted:Intriguing idea. Does the material have enough strength to handle the stress or can you get them 3D printed in metal?
Great question... I’m looking into both options. I can tell you from my initial investigation that 3D printed metal would be my preference BUT is going to be pretty expensive; like >$30 per car... they can’t be on a sprue for metal printing.
oh well, back to the drawing board.
