Lampshade with acrylic hangers

My Girlfriend had the idea to creat a lampshade with cheap acrylic hangers. The problem was, how to hold them together around the light bulb. So I design a support to hold 40 holders. At the end we just put 20 hangers because of the weight but the result looks good.

So to realise this you have to print the central part and 4 side parts.
You need acrylic hangers (diameter around 8 mm )
