I love a good toy construction set, whether it’s building bricks, snap-together circuits, wooden machines, foam blocks, or kinetic sculptures.

Now I’ve stumbled across another in the form of STEM Master, which makes use of a variety of piece shapes that allow you to engineer all sorts of buildings, vehicles, creatures, geometric shapes, and more. It’s one of those things where your imagination is the only real limit, and it comes with a guide for making 42 designs, from easy to advanced in difficulty.

The 176-piece kit is $22 on Amazon and comes with its own storage tub with handle.
