3 way joint

This is a basic Kawai Tsugite joint or 3 way joint. This is also a fun toy. I really recommend this for fun and learning. (Also I scaled it up in the photos, see what works for you.) Don't have a printer? https://www.etsy.com/listing/761985256/3-way-joint?ref=shop_home_active_1 https://youtu.be/lnttxL294ps
