World's tiniest circular saw 3D-printed into improbable existence

You've heard of the world's smallest violin. Now meet the world's tiniest working circular saw. Unlike the violin, it's real. It's the creation of Lance Abernethy, a 3D-printing wizard with a penchant for creating miniatures.

Abernethy is shaping up to be an expert in miniscule 3D-printed power tools. Earlier this year, he created a mini cordless drill with a tiny power button driving an itty-bitty metal drill bit. It even has a black plastic case modeled after the ones the big drills are carried in.

The circular saw has a lot of the same features as its bigger brethren. There's a handle sized for Stuart Little, a spinning metal blade and a power button to turn it on. The blade has a guard over the top to protect your fingers.

The wee saw doesn't have the oomph to cut through wood, but it might be able to tackle some softer materials, like a marshmallow Peep or a slice of brie.

Abernethy uses Onshape design software and generates the working models with an Ultimaker 2 3D printer. At this rate, he could have a full contingent of Lego minifig-sized tools by the end of next year. He just needs to print out a sander, an impact wrench and a reciprocal saw, and then he can build a tiny house with his diminutive power tools.
