# LED Noodle Shop Sign
## Overview
## 3D Printed LED Noodle Sign
3D print parts to make a glowing neon-like noodle shop sign. This features flexible LED filaments that are press fitted into channels in the 3D printed sign.
This 3D printed sign features three LED noodles that are press fitted and shaped like a noodle, bowl and chopsticks.
## Light-up LEGO Builds
Wires are cleverly routed behind the sign and it’s powered by a coin cell battery holder.
The wires from the LEDs are routed through the built-in door on the roof top of the noodle shop.
## Hidden Battery
This 2x CR2032 coin cell battery holder features a on/off switch and fits nicely inside the LEGO noodle shop.
## LEGO Compatible Add-on
The 3D printed noodle sign features a mounting bar that can be fitted onto an existing LEGO brick for easy attachment.
## Prerequisite Guide

# LED Noodle Shop Sign
## Circuit Diagram
The diagram depicts routing of the LED noodle VCC and GND wires. The various wires are press fitted into the channel of the 3D printed holder.
The LED Noodles are wired in parallel with the voltage and ground wires connecting together.
The red and blue lines represent wires that will be connected to the LED noodles pins.
Each wire will require a unique length that can be cut to size when installing to the 3D printed holder.

## CAD Files
## CAD Parts List
STL files for 3D printing are oriented to print "as-is" on FDM style machines. Parts are designed to 3D print without any support material. Original design source may be downloaded using the links below:
- Noodle Shop Sign.stl
- Wire Holder.stl
## Build Volume
The parts require a 3D printer with a minimum build volume.
- 146mm (X) x 164mm (Y) x 50mm (Z)
## Transparent Filament
For best illumination, we suggest printing the parts in translucent / transparent PLA filament.

# LED Noodle Shop Sign
## Wiring
## Join Halves
The sign and wire holder are glued together with super glue. Join the two halves together with the flat bottoms facing each other.
Danger:
## Assembled Sign
Allow the glue to dry before handling.
## Install Noodles
Reference the photo for correct placement. Install the noodles into the sign by insert the ends through the loops using tweezers or flat nose pliers.
Press the rest of the noodle into their corresponding channels.
Red noodle for the bowl. Yellow noodle for the noodle. Blue noodle for the chop sticks.
## Noodle Wires
Flip the sign to show the wire holder face up.
Measure and cut wires to create the channels for the three noodles.
Leave a minimum of 3in(76mm) of length for the last VCC and GND wires so they can be connected to the JST battery socket.
## Tin Wire Tips
Use wire strippers to remove a bit of insulation from the tip of each wire.
Add a bit of solder to the tips of each wire. This helps prevent the strands of wire from fraying.
## Connect Wires
Solder the wires to the various noodles. Use Tweezers to help keep wires in place while soldering.
## Solder Wires
Continue to solder the wires to the ends of the various noodle.
Orient the sign for better handling for more comfortable soldering.
## Continue Soldering
Get the next round of wires soldered.
Take your time, soldering two wires to a single pin can be tricky!
## More Soldering
Keep going. Almost there.
## Last Ends
Finally, solder the remaining wires to the LED noodles anode and cathode.
## Connect 2-pin Cable
Solder the last two wires to the 2-pin JST cable. Add pieces of heat shrink tubing to help insulate the exposed wire.
## Wired Noodles
Take a moment to take all of the wires have been properly soldered.
## Circuit Power Test
Connect the 2-pin cable from the LED noodles to the coin cell battery holder.
Use the built-in slide switch to turn the circuit on and off.
# LED Noodle Shop Sign
## Assembly
## Install LEGO plate
The sign features six holes that press fit onto existing LEGO pieces.
This build used a 1x8 plate for attaching to the trim of the building's roof.
Additional LEGO plates are added to the exterior of the build for best placement.
## Cable Management
The cable can be fitted through the door on the top of the roof.
## Store Battery
The coin cell battery holder can be stored away inside the apartment upstairs.
