Duplo construction car addons

NO AMS needed!

My 3-year-old son is obsessed with construction vehicles, especially the ones with moving parts. He loves his Duplo sets, but he always wants to attach tools to the longest arm possible. Since the existing extensions weren’t quite enough for his imagination, I decided to step in!

I designed and 3D-printed a drill, a roller, and extra connectors so he can build even longer arms for his machines. Now, he can create massive excavators and construction vehicles with crazy long reach—exactly how he likes it! Seeing his excitement when he stacked everything together was totally worth it.

I use extra reinforced walls so that it can withstand playing.

You need to use some glue!
