39. Custom Connector
A great print idea and execution to get things moving! The creator of this said that the force of the joint will be downwards so it doesn’t need to be as strong as you would think. There are many ways to strengthen this connector such as making it thicker or adding a gusset underneath. Just make sure it’s not printed in PLA!
