Mk IV Arc Reactor Light up using Samsung Galaxy 5 battery

thingiverse

I reworked "Iron Man- Arc Reactor" by Thebak3 to suit my needs. Initially, I noticed that the lower part of his design was an oval shape, so I converted it to a round shape that can be screwed together with the top piece. Additionally, I found that there wasn't enough tolerance between the top and bottom parts, so I reduced the size of the top by 3%. To enhance the appearance, I added a file as an insert labeled "Arc Reactor" and embedded blue LEDs into it, then wired them together to achieve the desired effect. The entire setup runs on a 3.85v cell phone battery (Samsung Galaxy 5), which I modified by adding belt loops and terminal holes for easier handling. Once printed, I inserted metal contacts for the battery and connected them to a molex adapter for easy disconnection. Moreover, I discovered a 3.7v dc output transformer that converts ac power and wired it with another molex, allowing the final product to be used either with a battery or from the wall outlet. To illuminate the "arc reactor" print, I inserted LEDs into each hole and hot glued them in place, followed by adding a resistor to each one. I then connected the wiring and secured it with hot glue to prevent any positive connections from touching negative ones. With ample space available, the wiring didn't need to be perfect. To complete the setup, I wired in an on/off switch and added a permanent resistor to reduce the brightness of the LEDs, also adding a molex connector for easier handling. When printing the "Arc reactor," it's recommended to use transparent or translucent material for the best visual effect. The diameter of the arc reactor is too large, so it's suggested to downscale it instead of sanding it down, which was my approach due to time constraints. However, a more precise method would be to adjust the file size. Another issue I encountered was that the thread pitch was off, so I used a dremel to auger out the bottom until it fit properly. Someone with better skills may be able to fix this issue by modifying the files. Please note that this is my first completed project after acquiring my printer about a week prior and rushing it for Christmas. Be kind! If you have any questions, feel free to ask.
