Kendama

I still play with my toys from high school and they are just as fun today. When my wood kendama's spike started to dull, I decided to reverse-engineer it so I could easily print new spikes whenever mine wears out. This was super easy and a great gift for kids during the holidays. I printed my ball in one piece but it warped slightly on the underside, so I also created files that split the ball into two halves, which can be printed separately and glued together to prevent warping. To get an authentic feel when using a kendama, make sure you get the weights right. I weighed my wood kendama to estimate the weight of the components in Simplify 3D's mass feature. The ball should weigh about 73 grams and the cup plus stem should have a combined weight of 64 grams. When using your slicer's mass estimate feature, remember that it includes the weight of the support structure, which you can use when printing the stem and cups.
