Christmas Fireplace With Real-Time Rotating Flames

A Cozy Christmas fireplace featuring a rotating translucent flame drum, LED backlighting, and a fully enclosed stone-style shell. Powered by a small N20 motor and USB-C rechargeable module, it creates a realistic animated flame illusion. Includes decorative stockings, gifts, garlands, and faux wood logs to complete the festive look.

Filaments

Flames Slide: Black PETG + Red PETG + Orange Translucent PETG + Blue Translucent PETG

Fireplace: Matte Latte Brown + Rosewood Wood PLA

Decorations: Green PLA + Red PLA + Brown PLA

Internal: Matte Black PLA

Printing 

These prints require your plate to be VERY CLEAN as they will push your printer's capabilities to achieve the best results possible. I recommend washing your plate with hot water and dish soap before starting.

There are 3 plates to print:

1. The Flame Slide - This is the slide that the light shines through to create the simulation
2. The Main components - These are all the structural components for the fireplace
3. The Accessories/Decorations - These include the Pine Garland, Wood Logs, presents and socks

(I recommend printing them in that order)
