I originally printed a bunch of these small ones to give to my friends. One recommend a large one. I didn't stop there, I added an ESP for use in home automations using the WLED project. Scale them to fit your needs!

Supports were not needed for the smaller dumpster and fire, the larger you go you will need something in the middle. The 170 percent dumpster has an example of a support added. These will fit a tea candle led.

Dumpster parts
Filament - Any, only real requirement is Clear if you want to get the best of the WLED option.

Paint for smile - White, black, even add a red tongue.

Make or invent your own LED option 
Here are some options I have come up with but truly any led would do!

ESP - Any ESP8266 will work, I used a WEMOs D1Mini - https://www.amazon.com/gp/product/B0B4D7BQHV/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1

WS2812B addressable LEDs - https://www.amazon.com/gp/product/B088BPGMXB/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1

You can wire directly to the D1Mini for 5V by standard micro usb adaptor. I only used 14 addressable LEDs on mine, but you could add more.
