Building the Alphabet, One 3D-Printed LEGO-Compatible Letter at a Time

Posted on October 27, 2025

I’m diving into a fun and colorful 3D-printing project: creating the entire alphabet — A to Z — as LEGO-compatible letters! Each letter will be printed in a different PLA filament, making this a vibrant mix of colors and brands. Each one is giving me a place to stick those LEGO bricks I love to step on in the dark. Along the way, I’d love your input — comment or tag at the bottom of each video your favorite filament brand or color to inspire the next letter. You can follow the series and watch all the letters as they’re added with this playlist: Watch the full LEGO Alphabet series on YouTube and check out links to all the brands and colors I have used below!
