The two outer tiny blocks have the size of the margin and the center tiny block takes the remaining space. To accomodate 0.2 mm margins at the outside faces of the part, the small blocks are split further into three tiny blocks per dimension. Internally, each block consists of four small blocks.īy default, double sized blocks are created that consist of eight small blocks.Īll blocks are placed using coordinates of the small blocks so that they can be placed at 'half' positions. Pin Hole, Axle Hole, Pin, Axle and Solid. The system I came up with assembles the parts out of five basic blocks: I got the idea for this project when I was building with Lego parts and wondered how many of the common parts can be described with a simple rule set. I made a web app that lets you design your own Lego Technic parts and save them as printable STL files.
