Duplo x Tinkertoy

While looking for an option to allow my daughter to play with both her Lego Duplos and Tinkertoys, I found no solution that I liked. I decided to design something myself.

It is a simple 2x2 Lego Duplo "style" brick but with two distinct differences. On top and bottom there are holes which allow a plastic Tinkertoy rod to be inserted. This allows two-way interoperability to foster creativity.

You can use supports, but I was successful printing it without.

I have included the .STL and the .GCODE I used.

Enjoy.
