Simple Locking Puzzle

I wanted to model a sliding and locking puzzle like the wooden ones you typically see as stocking stuffers. This is a simple and quick print and the pieces easily slide together. (If you can figure it out) JK, there is a tutorial below with images. ASSEMBLY Step One: Start with the complete oval shape. Step Two: Slide one of the open interlocking ovals up onto the complete oval with the opening facing forward. Step Three: Slide the second and final open oval interlocking piece with the gap facing downward through the middle opening of the closed oval. Step Four: Line up the opening of the second open interlocking oval with the closed edge of the first open interlocking oval. Step Five: Slide the second open interlocking oval down. (There will be quite a bit of resistance) There is less than a 1mm gap between the pieces here from PLA shrinkage. (Your milage may vary) But I promise it fits. It must be this tight so the puzzle locks together.<img src="https://makerworld.bblmw.com/makerwor
