Put the ten pieces together to form a pyramid. It's harder than it looks, but the completed puzzle will look great on a shelf. Not as nice as the wood and steel original, this version is cheaper and fun to make. For an easy print, do what I did and print the balls in halves and assemble them. Wood filament for the board and metal filament for the balls would look really cool if you have some lying 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, 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 assembling them (and to provide strength against shearing), choose 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 ten whole pieces or twenty half pieces. Unless you have awesome cooling, make sure to print more than one piece at a time (probably at least four). Insert filament in the holes and cut it to form small pegs on one side. Then glue and snap them together on the other side. There is a small fillet on the rim of the ball halves to allow for first layer squish. There is also 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. Depending on your slicer and printer, you might still have to do some drilling, but let's hope for the best. Put the glue in a small bead all around the filament "pegs", then snap them together and hold or clamp them.
