🎢 GBC 60 Funhouse (42145 Alternate Build) – It Finally Works! 🎉

After a lot of building, tweaking, and fine-tuning, the GBC Funhouse is finally running reliably! 🎉

This is a raw work-in-progress video showing the module in action with all its moving mechanisms and endless stream of GBC balls.

The GBC Funhouse is an alternate build created from the LEGO Technic 42145 Airbus H175 Rescue Helicopter set, featuring a playful funfair-inspired design and multiple synchronized mechanisms.

What do you think? Any ideas for improvements before the final showcase video?

GBC 60 “Funhouse” is coming soon!

The latest alternate build for set 42145 is almost ready, and this one is all about movement, flow, and a bit of chaos in the best way possible.

Expect a compact but lively Great Ball Contraption module with plenty of character. This GBC features a lot of gearing throughout the build, driving its different sections in a compact but efficient way. It creates a smooth and reliable ball flow, while still keeping that playful “funhouse” feel 🎪⚙️

Still finalizing a few details, but it’s already turning into a really satisfying loop to watch.

More soon once it’s fully running.

One LEGO set. Multiple incredible builds.

Your LEGO Technic set doesn’t have to end up on the shelf after one build.

With our Building Instructions, you can transform the same set into exciting new Great Ball Contraptions—each teaching different mechanisms, engineering principles and building techniques. And if you’re ready for even more…

Our Combi Packs bundle multiple alternate builds for the same LEGO set, giving you more projects, more learning, and more value from the bricks you already own.

A few weeks ago we showed you an incredible fully functional LEGO record player built by one of our customers… and you loved it.

Now we’ve got something even better 👀

This new video shows our custom LEGO turntable needle performing LIVE at Oeiras BRInCKa 2026 — and yes, it’s playing real records.

Huge thanks again to Jorge Pereira from Portugal 🇵🇹 for pushing this build to the next level.

Seeing it in motion, in a real event setting, makes it even more impressive. This is what happens when creativity meets precision engineering. 🧱💡

The Secret Behind a Reliable GBCs

Ever wondered why some GBCs run smoothly for hours… while others can jam after 2 minutes? 🤔⚙️

Designing a reliable Great Ball Contraption is more than just moving balls from A to B.
Every module is a balance between:
🧱 structure rigidity
⚙️ gearing & timing
🎯 ball flow consistency
🔋 power efficiency
👀 and of course… satisfying motion

One tiny adjustment can completely change how a machine behaves.

That’s actually one of the things we love most about designing Great Ball Contraptions — combining engineering with creativity to create something mesmerizing to watch.

What is the most challenging part for YOU when building GBCs? Love to hear it!
