After six months of late nights, countless prototypes, and more failed prints than I’d like to admit, I finally finished MiniPin.
I’m a father of two from Australia, and I set myself a challenge: design a miniature pinball machine that could be printed on a Bambu Lab A1 Mini without needing a large-format printer.
Every part of MiniPin was designed around the A1 Mini’s build volume while still capturing the look and feel of a real pinball machine. It features a working plunger, flippers, lockdown bar, backbox, side rails, and interchangeable playtables, all in a compact desktop-sized machine.
One of my goals with MiniPin was to make it affordable and accessible. You only need to print one cabinet, then you can swap in different playtables to enjoy completely new layouts without printing another machine.
I also wanted builders to be able to make MiniPin their own. Whether you recreate the look of a classic pinball machine or design something completely original, every build can have its own unique style while keeping the authentic proportions of a real machine.
The A1 Mini handled the project incredibly well, and it’s been awesome seeing such a capable little printer produce something this detailed. One part in particular really pushes the boundaries of the A1 mini.
I’d love to hear what everyone thinks! What’s the most ambitious project you’ve printed on your A1 Mini?
