Update 9/1/23: Second “Inside" piece designed with a little more room for the blade and handle. Should help with printers that can't print tight tolerances.
I really enjoyed this toy, I just wanted to make a few changes. I started with a black slate taking design ideas from the original to get started. The biggest issue was the way the two pieces went together. You couldn't tighten them without inhibiting the movement. And they would get loose with lots of playing. So I made a device that lets you tighten a nut and bolt fully so it will not get loose with play. The other change was to make it so you don't have to open it too far to get the blade to release. And the last was giving the knife some grip. I was dropped it so many times. I have made two handle designs. Enjoy.
