Warning: 

This guide is a work in progress for printing and assembling the Overwatch Lucio blaster as well as connecting the electronics. [Part 1](../../../overwatch-lucio-gun-pt1/overview) and [Part 2](../../../overwatch-lucio-gun-pt-2/blaster-circuit-integration?view=all) of this series show how the circuits are created.

Get ready to go into 3D printing production -- there are 42 parts to print for Lucio's blaster! Download the model files [here](http://www.thingiverse.com/thing:2034258).

You can choose to print in a single color and then prime and paint your parts, or use colored filaments as seen here. The frontDiffuser part should be printed in a translucent natural filament in order to allow the LEDs to glow through with some diffusion.

These are the filament colors I used, printing on a combination of an Ultimaker 2+ and a Printrbot Metal Simple:

- Ultimate Blue PLA by Ultimaker
- Light Green PLA/PHA by Meltink3D
- Black PLA/PHA by Melktink 3D
- Orange PLA/PHA by Meltink 3D
- Dark Gray CPE by Ultimaker
- [Natrual Translucent PLA/PHA](https://www.adafruit.com/products/2451)
- [Silver PLA/PHA](https://www.adafruit.com/products/2063)

The three largest parts were printed on a BCN3D Sigma printer in gray and black PLA/PHA.

All of the parts can be printed on a typical 3D printer's approximately 8"x8"x8" bed with the exceptions of the frontFace, frontBase, and frontCrown parts, which are quite large, so you may need to slice these into sections for re-assembly  later

After printing the parts and cleaning up the supports, you can dry fit them to make sure everything will go together smoothly.

## Circuit Building

![](https://cdn-learn.adafruit.com/assets/assets/000/038/531/medium800/gaming_Lucio_metroCircuit01.png?1484673711)

Warning: 

The music, sound, and lights circuits follow the blueprint [set out in part 2](../../../../overwatch-lucio-gun-pt-2/blaster-circuit-integration?view=all) of this series, but now we're transferring things to PermaProto boards. 

You can continue to use the Metro and Music Maker MP3 shield, as seen in the circuit diagram above, or move to the smaller Feather M0 Basic Proto with MusicMaker FeatherWing. Be aware, however, that the Feather is a 3.3V board and will need a level shifter to communicate properly with the NeoPixels.

In the diagram you'll see various parts labeled "JST" -- these are connections that can be made using multiple conductor JST connectors (or other interconnects of your chosing) in order to assist with assembly. It can be tricky to insert things such as speakers, lights, and buttons for triggers while they're connected to the circuit, so these will allow you to plug them in as you go.

Warning: 

For assembly, I used [M4 x 30mm socket-head screws](https://www.mcmaster.com/#91292A130), [M4 x 14mm socket-head screws](https://www.mcmaster.com/#92290A150), [M4 hex nuts](https://www.mcmaster.com/#90592A011), and [M4 x 0.7mm thread ](https://www.mcmaster.com/mv1484837058/#catalog/94180A351)[brass heat-set inserts](https://www.mcmaster.com/mv1484837058/#catalog/94180A351) on the top and front sections. 

All other parts were glued with A6000 adhesive.

## Closure

1. connect the panel mount USB cable to the primary PowerBoos, then run the female end through the **lower** hole on the left side of the gun, this is for battery charging later
2. run the two tilt switches through this same hole so they may be adjusted for tile later, then affixed to the side of the gun and covered with the **plug\_lft**
3. close up the gun by pressing the top/speakerMnt assembly down the rest of the way
4. fit and glue the **tab\_lft** and **tab\_rgt** into the **body\_top** and then into the **slot\_lft** and **slot\_rgt**  receiving slots respectively
5. test out the gun to make sure everything works!
