Dumbell Bar Connector M30x6

Introducing the Dumbbell Connector! 

This handy 3D model is perfect for connecting two dumbbells together and turning them into one barbell easily. This connector features an M30x6 thread.

I recommend using at least 50% infill for durability. Be sure to print the test model first to ensure everything fits just right! 

Don't exaggerate with the weight, it's still just plastic.
