This is a design for an LED illuminated pedestal I created to display Lego helmet kits. Lego has created a number of these as can be seen here: https://www.lego.com/en-us/search?q=helmet
I currently own the Batman's cowl and Iron Man sets, and the pictures show how these look with the final product.
I designed this so that most parts can be printed without supports. There's a hole in the front to snap in a logo to match the helmet being displayed along with two smaller holes for additional LEDs to illuminate the logo. I'm using translucent filament for the parts I want to illuminate (the bottom, the lid, and some of the logo).
I've included models for Batman, Ironman, and two Star Wars logos (one for the Empire, and one for the Rebellion) which should cover most of the helmet kits Lego makes. The logo parts are the only ones I printed with supports.
The LEDs were purchased from a company called Briksmax This company specializes in LED light kits that can be used to enhance Lego model sets, but they also sell individual lights in their DIY section for custom projects (They have a store on Amazon as well if you don't want to purchase from their website directly). In the pictures, you can see I'm using their lighting kits for the helmets themselves. So, I just needed to add a couple of white LED strip lights for the base and white LED dot lights for the logos and wire them into the LED kit of the helmet. If you're not using the helmet kit, you would need to add a usb power connector to the mix as well. I've included a picture of the inside of the pedestal to show what the wiring looks like and make wiring easier.
