Educational Spirograph

thingiverse

This spirograph is designed specifically for use on a laser cutter. If you're looking for similar designs for 3D printers, Thingiverse has numerous options available. # Remix Details ## Paths Joined When I worked with the original file, I noticed that most of the paths were not joined together, which made placement quite challenging. To resolve this issue, I manually joined them and created `sheet{1-3}_joined.svg`. Additionally, I saved some Illustrator versions as well since my Illustrator software couldn't open certain SVG files, despite being created by Illustrator itself. Inkscape 0.92 can handle these files with ease. To clarify: the files labeled `sheetN_joined` in ai, svg, or dxf formats are variations of the original `sheetN` files where I merged the anchor points into a single line for improved and faster cutting on the laser cutter. ## Resized for A4 Paper I also resized all the pieces and adjusted the two main rings to fit perfectly onto an A4 sheet of paper. Furthermore, I carefully selected pieces to fit within a 600x400mm sheet of acrylic. To be clear: the files labeled `600x400_joined.ai` (and its open-source counterpart, `600x400_joined.svg`) represent a rescaled subset of the three `sheetN_joined` files where I picked elements to fit inside sheets of 600 x 400 mm acrylic. The `_joined` suffix emphasizes that the paths are joined together. # Wooden Socket I also utilized a CNC router to cut out a wooden socket. A rectangle was cut for an A4 sheet, with a pocket of 5.6mm deep designed specifically for 5mm thick acrylic sheets. This socket holds the sheet of paper and the outer ring in place, making it easier to draw with the spirograph.
