Summary

When I was at school we used to make such a device with a saw. Here, of course, I immediately fired up the laser and made myself a pantograph, which magnifies by a factor of 2. It could be screwed together with screws, which would increase the accuracy even more and would also be easier to assemble. But I wanted to make everything out of wood for the time being. The holes could also be adapted so that the pen fits better. I wanted to make it a bit bigger so that I could use more pens, so I wrapped tape around the pen.
