This model is a JDM Brand tsurikawa!

This tsurikawa is 11cm wide, 7.5cm tall and is 1cm thick.

Tsurikawas are designed to work with a 1 inch (25mm) nylon strap, 2x M4x10 screws and nuts, and a 3D printed strap lock (the models for the strap locks are available free - check out my other designs!)

The images show the final product - an assembled tsurikawa!
