Stargate with dialing effects

This design is a replica of the SGC's Stargate and its ramp. It has been simplified to accommodate smaller printers but remains fairly screen-accurate.

The gate itself has a 117mm(4.6") diameter and has been successfully scaled up to 250mm.

I provide the 123D files of my design if you want to modify it (for example to scale the stepper motor hole in the gear if you wish to print a bigger version).

Assembly:
Please use the exploded views I provided as reference, it is very straightforward.

Electronics:
At the moment I did not write instructions regarding the electronics, but I made a part list and include the arduino sketch if you're willing to attempt it yourself. Note: if you're printing a bigger/thicker version, you could use regular LEDs instead of surface mount.

Parts:
- 7 surface mount red LEDs
- 4 surface mount white LEDs
- 2 or more blue LEDs
- ULN2803 (or equivalent)
- 28YBJ-48 stepper motor
- Any Arduino that fits in the base (I used a mini)
- Momentary
