Spirograph!

thingiverse

Create your own 3D printed Spirograph! This project utilizes Catarina's Spur Gear Script for the intricate gears, but modifications have been made to add a unique touch. OpenSCAD files are provided for customization. Share your masterpiece if you make one; unfortunately, the printer for this creation is not yet complete. The holes on the gear don't align evenly due to a spirograph curve, and there's a possibility that they may be too small. Feel free to adjust the OpenSCAD file accordingly. An additional .stl of an unusual gear is included for design purposes. A recent update allows you to choose between a ring or square stator, but use this feature with caution due to a rendering issue. If you encounter any problems, please let us know. Instructions for using the printed parts are as follows: print the first part, then the second part. Insert a pen in the hole and rotate the gear. Enjoy your hypotrochoidal adventure! For tips on creating compatible gears (rotors) and frames (stators), remember that their diametral pitch should be equal (number of teeth divided by pitch diameter). Gear irregularities and shrinking plastic may cause tight fitting, so adjust the tooth widths accordingly. An oval design can be achieved if the rotor's diameter or teeth number is half that of the stator. Experiment with different proportions and prime numbers to discover various patterns.
