I wanted a way to mount some LEDs to my Anet A8. I also wanted to diffuse the light slightly.
This is my solution.
It is made in three parts; left side, top and right side. Although this would fit on my print bed I decided to make each part in two pieces. You will need to glue the parts together. I used CA extra thick.
There is a dado in each part so the LED strip has a way to be held in.
Each part just clips on the frame of the printer no fasteners required.
Update:
The LEDs I used were sold by Rextin, and may no longer be available, looks like they updated their design, here are the dimensions of what I did use so you can find an alternative 9.8 x 0.6 x 0.4 inches.
