Weird hope engine
So the train armour thing really stuck with me and im going ahead with the sculpture of it.
I found a STL file on https://www.thingiverse.com/ which is a reliable open source platform chock full of 3D printing files, with a minimum amount of printable guns. Brucey bonus.
I manipulated the original file in AutoCAD Inventor, shortening the carriage length. I also added some props to give the design more structural integrity while printing; these are visible in yellow on the screenshot below and will pop out when finished. I chose a quick printing time because it's only going to be used to create a silicone jacket mold, and so doesn't need to be super sturdy.
I would usually use Autodesk Fusion 360 for a job like this, because it's free to educators, students and some start ups, and does the same thing as AutoCAD. But this was the software on the connected laptop at the time so here we are.
The train file took roughly 11 hours to print on the lowest integrity setting. The highest setting would have taken 55 hours!
