Last month I had a solo exhibition which featured a series of paper houses, planes, and cars that I designed in Illustrator and cut out with a laser cutter. Now I'm making those files openly available for anyone to download.
They aren't easy to make, and definitely require a little patience and some skill with gluing small parts, but I hope you'll give it a try and support your local makerspace.
This house was "re-designed" for the laser cutter but is almost identical to the house in Chris Ware's graphic novel "Jimmy Corrigan The Smartest Boy On Earth".
This model is loosely based on a Volvo.
This is an almost to-scale model of a 747 if it didn't have any curved surfaces.
One fun thing with these is that you can scale them up or down to almost any size you want.
