LED Dragon Egg with battery

Remixed this awesome design of an dragon egg from @DoritoMojito on myminifactory:

It now fits a threaded insert in the bottom so it can be lighted from the inside.

The base of the egg is designed specifically for the following parts:

• Battery holder https://smile.amazon.de/gp/product/B0823WK4CN/ref=ppx\_yo\_dt\_b\_asin\_title\_o04\_s00?ie=UTF8&psc=1
• Power switch https://smile.amazon.de/gp/product/B007QAJLDE/ref=ppx\_yo\_dt\_b\_asin\_title\_o05\_s00?ie=UTF8&psc=1

Additional you need the following:

• 5mm LED
• Soldering iron and some solder
• CR2032 battery
• short wire (2.5cm) Assembly should be obvious from the pictures.

Print settings:

• until layer 79 i used 20% infill
• from there to the to 0% so the light can pass through
• use transparent/translucent filament with 2 or 3 walls (you may try non-translucent filament with 1 wall but I haven´t tried that yet)
• you also need to make a hole in the middle

                 → right click the model in Prusaslicer → add modifier Cylinder

                 → scale it to 12mm X/Y and 16mm Z

                 → position X/Y =0 so it sits right in the middle of the egg

                 → right click in the cylinder → Layers and Perimeter → Bottom Layer 0

• I got some issues at the top as you can see in one of the pictures, but that was probably due to the filament i used. Maybe using a little bit infill in the top are would improve it.

If you like the egg you can use the LED threaded insert in one of my other design as well:
