Quick animated display for my son’s fourth grade project about mining. 10 minutes in solid works. 10 minutes in inkscape. And 2 minutes on the laser. I use PETG filament to make the rivets for the joints, this is 3mm fluorescent green cast acrylic.
3d printer and K40 are great team.you can do magic if you use both of them.i like your project
That’s awesome. I wish this sort of thing was readily available when I was growing up as a child. Great work.
@Yuusuf_Sallahuddin_Y thanks. Our kids are exposed to such awesome things these days. When I was a kid I could only dream of such things.
Oh come on, the Atari 2600 was way better than 3D printers, tablets, laser cutters, etc 
Nice job by the way. 
@David_Cook Totally true. Also would be cool to have a dad like you that is capable of making awesome little gadgets like this for his projects.
