About this 3D model

This is done to real world scale. I took a spade terminal and measured the width which was 6.5mm. Then I took and printed the included image. And got myself a scale ratio. I have included a complete assembly stl, and the 4 stl's that made the assembly. So you can either build one with the pieces, or just print the whole item. I left a 0.1mm gap between the pieces since from the image that is what looked right. So everything should just slot together. The photo is of the first print I did, and sent to a friend as a gift. He did the finish work on it.
