Holder for easy mounting HobbyKing LED strips on Ultimaker.

So I had the "Turnigy High Denisity LED Flexible Strips" laying around. They are actually covered with sticking tape at the back, but it won't stick to well to the wood. Besides, I decided that for the ideal position I need to design a holder for them. And here it is. Just mounted it today and done first print - works very nicely - no clearance problems. Easy to assemble. Enjoy.

This is actually fully parametric in OpenSCAD, so you might adjust to different sizes of LED strips you happen to have.


So you need these LED strips:
White is obviously the best, I only had blue and red ones, so for now I'm using blue.

You need 3 pieces, 25cm each. They sell it by the meter, and you can cut it every 5cm (each 5cm piece has 3 diodes).

Then you print 3 pieces of led_bar and 6 pieces of led_hook. Mount bars on front, left and right of Ultimaker. Connect to 12V power source. You're done!

As for power supply - they require 12V and each 25cm bar takes around 120mA. So 3 take 360mA. I didn't want to overload the Ultimaker built-in 12V stabilizer, and since I had it laying around I added this: http://www.dimensionengineering.com/products/de-swadj - it's nice since it doesn't require any additional elements and has a screw you can adjust the brightness of LEDs with :)

I'm not able to get the OpenSCAD to work (it is the first try). I had to scale the hooks by 1.03 for a perfect fit.
