3D model description

I made this Portal Companion cube with leds. it has an ATtiny85 that control the leds, you can set the light effect you want programming it.

You need to print the following parts:

Cube_Hollow x1
Corner_Gray_Down x4
Corner_Gray_Up x4
Corner_White x8
Bit x12
Center x5
Heart x5 (OPTIONAL)
Cover_Electronics
Cover_Simple (OPTIONAL, cover without housing for electronics)

NOTE: When you turn it on. At start it will light the leds with a bright white colour, after 5 seconds it will start doing the correct effect. This is due to the ATtiny85 loading the code.

ATtiny85 code for light effects:

This is the code i used in this project. Its a breathing effect with the leds set to pink.
There is a line disabled:
//loop_rainbow(curr_ms);

if you enable this removing the slashes, it will do a rainbow effect:
loop_rainbow(curr_ms);

Code:
