Lego Duplo compatible building block 2x2

A simple 2x2 building block compatible with Lego Duplo

• Rounded corners to make it suitable for kids
• No supports
• .step file for customisation

Dimensions are pretty much exactly from the original, I just made some changes to make it more suitable for 3D printing. (thicker walls, supports for bridging)

It's a very good fit with my printer, make sure there is no elephant foot on your print!
If there is one you can simply connect two blocks a few millimetres and wiggle them around a bit.

If you are still having problems feel free to change up the design with the provided .step file.
If you don't have any experience with CAD software you can also comment or send me a message and I will make a version with a loser/tighter fit.

P.s.: I‘m sure you can easily print it under 1h but my printer isn’t suited for high speeds.
 

Have fun printing!
