Hey, what an amazing job.
I run a 3D Printing material Company in Germany and we are producing a compostable flexible material and we printed toy tires already.
It would be a pleasure to print Cole`s Mech tire and to build it for real.
I just started to rebuild the Dragon Head for a special Diorama*.
Has anyone tried to find matching paint for Sand Green Pantone 624 C Pantone HEX 789F90 Red Green Blue (RGB) 120 159 144 (http://www.bartneck.de/2016/09/09/the-curious-case-of-lego-colors/)?
I found Revell Aqua Color Patina Green 36365 only, which is close.
