PVC fort building balls
Description
hi all, On Aliexpress and temu they sell plastic balls with sticks to build a fort. But the specs say 30cm sticks. so you need a crazy lot to actually build something big. i noticed a ball design from Shane7986 and adapted the design to use 16mm pvc tubing. The balls are rock solid and can handle a lot of abuse before they break. two length of tube are used: 46cm for straight connections. 67cm for diagonal connections. this will result in a 50x50 building grid. This was a present for my kids this Christmas. i printed about 60 balls and used 40 meters of PVC. yesterday we build our own big fort and used up all tubes. used about 40 balls. The balls are printed in PLA with 30% infill and 4 external perimeters. This video is dutch spoken, but you can skip to 5:40 to see the actual building https://www.youtube.com/watch?v=lQg-WAXn9A0
