Square Kumihimo loom

Kumihimo (組み紐) is a Japanese form of braid-making. Cords and ribbons are made by interlacing strands. Kumi himo is Japanese for "gathered threads".
This is a Square type so you can make flat kumihimo
No supports needed
you can scale up or down the kumihimo square
if you want you can cut and glue a foam board with silicon glue
if you dont want to print the tama, you can use any wood tweezers as weights
I added the tama file if you want to do it the "traditional" way the more weight the better
so you can print them with 50% or 100% infill depends of your taste
