Slider Puzzle. 3x3.

The ultimate test of brainpower: the classic 3x3 slider puzzle! Check out the photo - I'm afraid I'm not exactly a whiz at puzzles, and those last two numbers have got me stumped. Hopefully, you'll be able to figure it out. First things first, print out the frame and the number blocks. I've included both normal and mirrored versions because my printer had some issues with printing them correctly - yours might too! Just print one of the number blocks and see how it turns out, then use the corresponding files. Once you've got everything printed, assemble the puzzle by sliding the blocks into the frame and pushing the end piece on. As you do this, make sure that the two frame pieces fit together properly at the small divot in one corner. If they don't, double-check that all the support material has been removed from under the tabs. Smoothing out the block sides with some fine sandpaper will also help them slide more smoothly. If the end frame doesn't fit tightly enough, a tiny drop of superglue on the tabs should do the trick. To print this puzzle, use 0.1 layers, three perimeters, and 50% infill - and make sure to set support material everywhere for the best results. Be careful when removing the support from the blocks, though - you don't want to break off any edges. I used 3.5mm spacing and one interface layer when I printed it, and it came apart just fine. To make it a bit more challenging, try using different colors for the blocks and highlight the numbers with a felt pen. Scramble them up and see if you can arrange them in order from left to right. Good luck!
