Portable Paddle

After messing around with bearings and magnets and spending lot of time to get those complicated stuff to fit together I was not happy with all that stuff. So I went back to a much simplier design, where no bearuings and no magnets are needed. Tension comes just from the plastic and so all you need is the 3 parts printed out, 2 pins (nails in my case), some wire, the female part of a 7mm bullet plug (I used this, because I have plenty of them in my spare parts box from unsoldering it from LiPos)
