GIANT Lego* Christmas Tree *inspired

Ellis and I made a Giant 3D printed LEGO Christmas Tree, we scaled up the LEGO Christmas tree six times to create a six foot Christmas tree.

Ellis and I decided to make some changes early on. I wanted to change the base (I didn't like the way it looks), so some design changes were made to the central structure to make sure we could ass the wooden base and metal pole.

This project was entirely 3D printed, showcasing a mix of different printers and techniques to bring it to life. The majority of the pieces were printed using a Bambu printer, while the decorations and presents were produced on a Mk4 Prusa for finer detailing. The tree itself required an incredible 50 kilograms of filament, given the print settings we chose to achieve the desired finish and durability.

A big thanks to Polymaker, who generously donated the filament for this project. To save time and ensure the tree had a polished look, we printed each piece in its final, correct color, eliminating the need for post-print painting.

However, some of the central components of the tree were too large to fit within the print volumes of the printers we had access to. To overcome this, we used a method called "glooping" to assemble these oversized parts. This involved printing the large sections in smaller, manageable pieces, which were then carefully bonded together using a strong adhesive. Ellis modelled these large parts with extra supports and connection points to ensure everything fit securely and held together beautifully.

The result was a seamless and sturdy final structure, ready to take centre stage!

I think the hearts might be my favorite part of the project. They’re designed to print upright, requiring just a few supports, and they clean up beautifully after printing. To add a festive touch, I printed a few extra components to create presents to complement the tree. For the color scheme, I opted for a classic red and gold theme, which worked perfectly with the overall design. The Polymaker Gold filament deserves a special mention—it’s absolutely stunning and added a luxurious finish to the decorations.

To give the LEGO-inspired Christmas tree a warm and festive glow, remote-controlled tea lights were incorporated into the design as part of the decorations. The tree's candle-shaped elements were specifically 3D printed with pre-designed holes to house both the tea lights and the remote module (linked in the project details). This thoughtful integration ensured a seamless fit and easy access for light installation.

The remote-controlled tea lights were chosen for their practicality and convenience. With a single remote, all the lights could be turned on or off simultaneously, making setup effortless and ensuring consistent lighting at the press of a button. This feature was especially useful during filming and display.

In addition to the tea lights, light-up baubles were added to enhance the tree’s festive charm. Using custom-designed, 3D-printed holders, these baubles were retrofitted with lights, allowing them to glow brightly while securely staying in place on the tree. The flickering effect of the tea lights and the gentle illumination from the baubles added depth and a cozy, candle-like ambiance to the overall design.

The tree’s star was also reprinted with intentional gaps to accommodate LED lights. These LEDs were then wired in, creating a brilliant and eye-catching topper that tied the lighting design together. While adding lights is an optional feature, it transforms the tree into a more practical and visually impactful decoration, making it feel like a true centerpiece for the holiday season.
