Impossible Kawai Tsugite - 日本の組み継ぎ

One Model, Infinite Satisfaction!

The best part about this model is its simplicity: you only need to print the exact same file twice. Simply print two copies of the same part, and they will lock together perfectly in three different directions.

This is the "Kawai Tsugite" (Kawai Joint), an ingenious traditional Japanese woodworking joint that seems physically impossible at first glance.

• 1 File = 1 Joint: No need for separate male/female parts. Just print two of these!
• No Glue Required: The parts stay together by a precise friction fit.
• Multi-Color Fun: Use two different filament colors for each print to create a stunning geometric contrast.
