I was think about what I should 3D print… any ideas

I am in the process of printing a Spitfire. Lovely project, it might even fly one day. And a Avocado Boat, might actually produce a tree.
There are some interesting little puzzles that are fun to print and to try and puzzle out.
Model of your home, model it and create a stl from that.
Or try the Marble Castle on Thingiverse.

A half cube with one hole in the top, one in the bottom, and loads of tubeing inside that’s complex for the sake of being complex.
