Mustang Mechanism Difficulty: ⭕Advanced This fully 3D-printable kinetic horse mechanism captures a running gait with smooth, lifelike motion. I’ve spent an inordinate amount of time refining the linkage so it feels as natural as possible.

The kit snaps together by hand—no tools required.

It makes an excellent gift or stocking stuffer for anyone who enjoys mechanical curiosities, and it’s also a proven seller if you’re adding new products to your 3D-printing business.

All linkage parts come on a sprue tree (much like classic model kits). It keeps everything organized, easy to track, and allows you to store or gift the print before assembly.

The build guide has been tested by friends and family, though I’m always looking to improve. At the end of the instructions, you’ll find a QR-code survey—your feedback is most welcome.
