Tenkara Line Holder

I am an advocate of tenkara - a form of traditional Japanese fly fishing. Modern Tenkara rods telescope and the line is a fixed length, usually around 12'. Between fishing, the line needs to be stored. This line holder does just that and then slips over the cork grip on the rod. It is similar to commercial Japanese versions but mine is smaller and wider and made of biodegradable PLA!

UPDATE: I realized that this thing did not need to be so wide, so I've created a narrower version that is 5m
