3D Printed Flying Propeller

In the past I have printed several models of flying propellers as they are great fun to the children I gave it to. I found some spare 608 bearing so I thought lets design a simple product which can make use of those 608 bearings to make a smooth movement. I make use of some screws for mounting. The would assembly will hold together with 3 screws and nuts. This makes it also easy if maintenance or replacement of gear is needed. For printing and assembly instruction, you will find a PDF file named 3D Printed Flying Propeller. Assembly video: https://www.youtube.com/watch?v=HwSm79Vpirw Have fun !!
