Jurassic Park fence light (half-scale)

Display stand: https://www.printables.com/model/1384162-jurassic-park-fence-light-display-stand

Materials used

• Blue and/or orange transparent PETG;
• Gray PLA (PolyTerra);
• Black PLA (PolyTerra);
• Arduino nano;
• WS2812b led strip;
• Wire;
• Hot glue;
• Two M3 bolts or small screws.

Printing instructions

Model	Supports	Infill	Filament	Orientation
Lens	No	100%	PETG	Normal
Base	Yes	20%	PLA (gray)	Upside down
Top	Yes	20%	PLA (gray)	Normal
Seal ring	No	100%	PLA (black)	Normal
Led holder	No	20%	PLA	Normal

Assembly

• Attach the lens to the top using hot glue;
• Solder the wires to the LED strip and cut it to length (2 LEDs);
• Glue the led strip to the holder with hot glue for added strength;
• Next secure the holder to the base with the two M3 bolts and lead the wires out the back;
• Now screw everything together and attach the wires to the Arduino like shown here.
