Use a different color filament for the blocks and highlight the numbers with a felt pen. I used 3.5mm spacing and 1 interface layer and it came apart ok. Be careful removing support from the blocks so you dont break the edges. Set support for everywhere for best print. Print at 0.1 layers, 3 perimeters and 50% infill. If the end frame does not fit tight enough put a drop of superglue on the tabs. Smoothing the block sides with some fine sandpaper helps as well.

If not make sure all the support is removed from the corners and under the tabs. Make sure these are together when pushing the end on. look under the two frame pieces and you will see a small divot at one corner.

After cleaning up the print slide the blocks into the frame and push the end frame on. Just print one of the number blocks and see how it comes out then use the appropriate files. I have included a normal and mirrored versions because for some reason my printer printed the normal as mirrored and vise versa so you will have to see which one your printer will do correctly. As you can see in the photo I suck at puzzles and cant get the last two numbers. I hope you enjoyed this instructable and the puzzles.The classic 3x3 slider puzzle to test your skills and patience. The puzzle pieces should be 25mm in the X and Y directions and the tray should be 92mm in the X and Y directions.Īnd that's all folks. You may have to resize the STL's in your CAM software.

You can then print and assemble your puzzle for your enjoyment. Continue selecting and exporting until you have STL's of all the pieces. If the puzzle piece is all there, you can go ahead and delete it or move it out of the way in Netfabb and move on to the next piece. I found it was easier to select the pieces if I first moved on row at a time away from the rest of the puzzle tiles.Īfter exporting a puzzle piece, open it up in your favorite CAM software to ensure your exported STL file had all the parts. Once you have them all selected, right-click and export them as an STL file. Next you'll want to hold down the 'Ctrl' key and select all the parts that make up one puzzle piece. You might have noticed that I have a little excess flower over the 'blank' space in my puzzle set, If your model does as well you can go ahead and select and delete it.
