Mini LET Joint Box

Overview

In February of 2025, three CMR students participated in the BYU Engineering Student Innovator of the Year Competition with an unique fidget box that uses LET Joint technology developed by the CMR.

Because it's all printed in one piece, it simplifies assembly and has a unique look! Now you can print your own fold-up box!
