Educational Spirograph

This spirograph is meant for the laser cutter. Thingiverse has many spirographs for 3D printers if you are interested. # Remix details ## Paths joined I was using the original file and realised that most of the paths were not joined, which made placement difficult. I joined them by hand and created `sheet{1-3}_joined.svg`. I added some Illustrator versions as well because my Illustrator can't open some of the SVG's, even though it was Illustrator creating them. Inkscape 0.92 can open them. To be clear: the files `sheetN_joined` in ai, svg, or dxf are versions of the original `sheetN` files where I joined the anchor points into a single line for better and faster cutting on the laser cutter. ## Resized for A4 paper I also resized all pieces and adjusted the two main rings so they fit exactly a sheet of A4 paper, and selected pieces to fit into a single sheet of 600x400mm acrylic. To be clear: the files `600x400_joined.ai` (and its open-source version, `600x400_joined.svg`) are a rescaled subset of the three `sheetN_joined` files where I selected elements to fit inside sheets of 600 x 400 mm acrylic. The suffix `_joined` emphasizes that the paths are joined. # Wooden socket I also cut a wooden socket on a CNC router. A rectangle for A4 paper is cut as a pocket of 5.6mm deep for 5mm thick acrylic. This socket holds the sheet of paper and the outer ring in place and makes it easier to draw with the spirograph.
