Portable Wool Caddy

At the request of my MIL, I designed and printed this portable wool/yarn caddy. She had seen something like it in a store for some ridiculous price ($70) and asked if I could make her one for when she's camping. The idea is you put your roll of wool on it, and attach a strap to the top hole and then it can hang from your wrist or something nearby while you knit.  The example she showed me was all lasercut thin plywood, so I adapted the idea a bit to round out the center post for more smooth operation. I designed one side flat for ease of printing. Enjoy!
