Octagonal 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 Octagonal Kumihimo
This Hybrid kumihimo can be used for round kumihimo or flat kumihimo thats the advantage
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
