Pretty inexperienced in blender but I make some basic designs to print on my 3d printer. I created 2 puzzle pieces, One with a hole, and one with a male end. I put some text on top of each, extruded it and made it a mesh. I used Boolean to cut a cylinder hole through a cube and attached the cylinder to the second cube and joined them, making 2 cubes total. Everything looks correct in both shaded and wire mode.
I extracted them to my 3d printing software, I use CURA. And it displayed differently. One is just a cube, no hole, and the other is correct. However when I printed, the opposite problem happened. The cube with a hole was correct but the other did not print the cube+cylinder piece, just a cube.
I am so lost on what could be happening. Any Ideas?
