3D Printing Today Spirograph

thingiverse

This is a revised post of this design. The initial attempt featured two gears, one of which was incorrectly sized. This new version has no bumps on the flat surface of its inner gear and left its edges unsmoothed, though I've added some minor mods inside that don't affect print quality at all. I have fond memories of playing with a Spirograph as a kid but often found it frustrating when one of the gears popped out, ruining the drawing in progress. Trying various commercial options here only yielded more disappointing results; that's why I made my own version. To improve its usability and overall experience, I created a capture ring along the edge of the inner gear to keep the rotating gear firmly in place, eliminating the problem of slipping. Additionally, I ensured the holes would fit a standard ballpoint pen at an affordable price point. As expected, this modification significantly reduced the frustration and increased the enjoyment level! For a deeper dive into 3D Printing, LOTS of topics beyond this design are discussed on the 3D Printing Today Podcast, lasting anywhere from 45-60 minutes per episode with hands-on insights. There's no fluff - just hard-hitting coverage on various 3D Printing, Design, and Capture techniques! Each week we delve into current events with a focus on facts over hype; cover multiple in-depth technical subjects and highlight an "item of the week". Don't miss it!

For smooth printing results, your printer should have at least a 6" x 6" area available on the X and Y axes.
