NASA designed a giant "space flower" that folds up small enough to fit in a rocket, then blooms open to block a star's glare so we can see its planets. Fold your own paper starshade that wraps into a spiral and opens with a twist, then test it with a torch.

Cut and fold a paper Snailbot, make it crawl by hand, then give it a brain and a muscle. An Obo Play (ESP32) tells an SG90 servo what to do, and a few lines of code make the snail crawl by itself.

Some people have stiff or sore hands and find thin pens, spoons and toothbrushes hard to hold. Shape the perfect grip with Play-Doh, measure it, then design a fat handle with three finger grooves in Onshape and 3D print it.

Make a free Onshape account, then design a hollow 5 × 4 × 3 cm box using just Sketch, Extrude and Shell. It's ready to 3D print and makes a great first CAD project.
