If you like that design and don't mind breaking the bread, by all means go ahead and let us know how it turns out. But you can find other ways to produce a good nunchucks case.
You can fold up and sew a bandanna around your chucks or get some nice silk material and that. Then glue a zipper or snap button to the flap. If you are not good at sewing, then buy a 99 cent bandanna and take it to a tailor.
Or I just received my first case in the mail. It came with my nunchaku from swordsswords.com. They are pretty heavy with each leg made out of 3 sections, two steel sections on the ends and a hardwood section in the middle. They are all black and is connected by a noticeably sturdy chain. The only reason I purchased these chucks is the case that came with them. It's made of some thin knock-off leather, with a zipper to open and close, and a weak loop at the top (for what purpose, idk). I got the chucks and the case for just under $5 minus the shipping and handling. A little more economical then just the case for $20.
