8: New LED stripe bracket

Then came the rainy day, I started the 3D-printer to print out the new LED stipe bracket. It's a 18 hours work and I prefer to stay home and watch over the printer when in work.

Much better design now and it's more stable too. But one thing I missed, the spiral is too short, should have handled the two mm thickness of the walls. No catastrophe, I can cut the stripe in the other end.

The LED stripe bracket installed on the diffuser extension tubes. I have taken a lot of flat images and the MasterFlat I made of these looks very good.
