This is a Helicone toy inspired by John Edmark's Helicone See this in action here: https://vimeo.com/607340603
This is not an exact copy - it's certainly inspired by the original but if you want one exactly like John Edmark's, you can buy them on his website or through Amazon.
For assembly instructions or if you want to try designing your own, I have written up an Instructable here: instructables.com/Print-a-Helicone-Tinkercad3D-Printing/
You can print all parts but I have a few recommendations for best results:
- the pieces are numbered for ease of assembly so you will need one of each part and then enough spacers to place one between each branch.
- Print the spacers in the strongest material you have as they are doing most of the work (I used PETG) - these will need a small amount of supports from build plate but are the only pieces which need supports.
- I recommend using a steel rod, rather than the printed one as they're just sturdier - if you're printing the rod, I'd use the most rigid material you have.
