The goal for this project was to create a puzzle cube consisting of 27 smaller cubes using the program TinkerCad. The puzzle must have 5 separate pieces and each piece must consist of 5-6 cubes. Each piece must be a separate color and must fit together to form a perfect cube. Making the puzzle cube was a fun, yet tedious task! It took a lot of patience getting each cube aligned properly and making a 3x3x3 cube in the end! On TinkerCad I only used 20mm x 20mm x 20mm cubes which is the standard size cube when you first drag your cub onto your work grid.
I started off by making a cube consisting of all 27 blocks and used subtraction to get each puzzle piece. By this I mean taking away several smaller cubes away at a time and and joining them together to make one puzzle piece. I made sure each piece went in the x, y and z direction. I was only allowed to have one flat piece which was this yellow piece shown. Because I had four cubes making up this one piece, I had to group them together to make one solid puzzle piece. To do that, I highlighted all of the pieces and clicked on the “group” button on the top of the screen. This allows me to move each piece at a time without the cubes coming apart from each other. I proceeded to do this with each of the five pieces, coloring them as I was finished. When I printed each piece, I selected .2mm for the option “layer height” in the Ultimaker Cura printing options. The Infill Density was set to 20% and generated support was on. The nozzle size used was .4mm and it printed at 200 degrees celsius on a 60 degree celsius printing bed. The estimated time for one piece was about 20 minutes and is estimated to use about 15 grams of material.
Below are the steps of how the puzzle fits together. By color coding each piece, it is easier to see them and how they fit together to make the perfect puzzle cube.
