4-way cross section connector for rabbit tunnel (Zippi / Omlet)

thingiverse

This is my first version of a 4-way cross section for the Zippi Omlet tunnel system. Our rabbits love it and with given 4 spare tunnel elements you can create a small playground. It is designed, so you can still print it on a normal Prusa MK3s. Just print the part 2 times and click it together. This is a first rough version, but it works. The next step will be to enhance the connector. When printing, you don't need any supports except for the places I marked in the picture (use paint-on supports)
