Inspired by magnets construction kits i wanted to design something easy to print and low cost for kids. With this they can construct structures... Big structures in a very low cost way! Apart from STL, I have also included DFX plans to laser cut it. You have to use acrilic or wood of 5mm thick. Please let me know if you cut it, I have only tested the 3d printed option. At first, maybe, you have to sand a little, specially the "vertex" part (named "union" and created with 3 parts). Hope you like.... and if you like print or cut some and give to childs.
