Everyone has their favorite LEGO keychain. Maybe it’s the Beskar slab GWP from May 2022, or a classic 2×4 brick in your favorite color. Personally, I’m rocking Spider-Ham on the keys to my LEGO studio. And builder Bricktacular Builds gives us a brick-built version of Hank Pym’s infamous tank keychain, along with a couple of Pym Particle Discs, all built to a 1:1 scale. While the whole setup is downright adorable, my favorite bit has got to be the use of this 2×2 socket to hold the tank’s cannon. It’s the perfect piece in the perfect color and at the perfect scale to anchor the build in microscale-reality.
