Micromachine Car and Truck

thingiverse

I didn't find any micromachines or miniature cars online, so I decided to build my own. A box car STL file is available for download and can be imported into another 3D modeling program where you can customize the design to your liking. All three models print without supports when oriented on their side. However, depending on your printer's capabilities, the window overhang may require additional support, but mine didn't need any. There are two micromachines in the photo: a real one and another that I colored with a permanent marker. I'm planning to paint the others with acrylic paint, which works well on PLA. However, I'm unsure about the wheels; if anyone has better options that roll smoothly, please let me know.
