Cube puzzle (x6), create 6 small cubes or combine 4 pieces of each set for 1 big cube

thingiverse

As a kid, I had six foam cube puzzles that combined four pieces of each set created a big cube. Using photos and Google Images, I managed to recreate all six puzzles. From photo to 2D pixel art design to SVG, import into OpenSCAD, extrude, and "reduce" with offset() to create a little tolerance, I got a puzzle that fits tightly in its storage frame and tightly enough to create the small cubes. As I'm still printing them all, I haven't found out yet if the tolerance is tight enough to create the big cube. Disclaimers: 1. I created this for hobby reasons, regardless of whether or not I'm capable of doing so. 2. I didn't check if there's already a set like this online. If there is, it's purely coincidental – I didn't copy or remix your work. 3. I don't know if these puzzles are copyrighted. I created them identical to the ones I played with 35 years ago, though they're smaller in size and have identical shapes. If anyone has a problem with me posting these puzzles here, please let me know, and I'll remove them. Source files are terrible at this time, so they're not included. If anyone wants the source files, I can arrange that. Important notes: 1. I eyeballed the tolerances, and they turned out nearly perfect. I want to change the tolerance of the puzzle pieces a little tighter and the storage frame a little less tight to compensate, but my skills are limited. 2. I printed these on my Ender 3 and Ender 5 in .2 resolution, and my printers and setup are fantastic (yes, I'm proud of that, but they're far from perfect). So the tolerances might work for me, they might not for you. I apologize in advance – please don't get angry if the print fails. 3. The color in the file names identifies the original puzzle's color. I suggest printing the puzzles in different colors as the small cubes are a single color and the big cube has two solutions: one mixed color, and one with a single color on each side. These colors, obviously, don't have to be the indicated color – you'll see what I mean when I add photos.
