Completed puzzle looks good on a shelf. Not as nice as the wood and steel original, but cheaper and fun to make. For a challenge, print the ball pieces whole. Otherwise, for an easy print, do what I did and print the balls in halves and assemble. Wood filament for the board and metal filament for the balls would look nice, if you have some laying around. While you're here, check out my other puzzle: [Identical Twins Puzzle](https://www.thingiverse.com/thing:2638467) If you can't solve this and want to give up, you can message me on Thingiverse, and I'll send you the link to the Youtube video with the solution. **Choosing the right model**: Since you use filament for aligning the halves when you assemble them (and to provide strength against sheering), pick the right model for your filament size. Print the 1.75mm halves if you have 1.75mm filament and the 3mm halves if you have 3mm filament. **Instructions**: Print 10 whole pieces or 20 half pieces. Unless you have awesome cooling, make sure that you print more than one piece at a time (probably at least 4). Insert filament in the holes and cut to form small pegs on one side, then glue and snap on the other side. There is a small fillet on the rim of the ball halves to allow for first layer squish. There is a significant fillet on the holes to prevent the first layer squish from shrinking the holes. This keeps you from having to drill out the holes. I suppose, depending on your slicer and printer, you still might have to do some drilling, but let's hope for the best. Put the glue in a small bead all the way around the filament "pegs", then snap together and hold or clamp.
