This is a very weird mechanism I found based on this video from thang010146:

The knob can only turn one direction and when it is turned, tensions the spring and provides a snappy turn. For now, it is a fidget toy, but I think I can use this mechanism in a more functional design.

No supports needed, printed with .2 layer height in PLA.

Can make an assembly video soon.

Introducing the Camera Cup! Using fidget spiral technology, the lens can expand and collapse. There is also a print-in-place lens cap that functions to hide your pens or other belongings. No supports are needed and there's a 3mf if you want yours to have a red line as well.

This design is inspired by Craighill's sidewinder knife. It is fully printed without supports, relatively easy to assemble and loads of fun. 

I will also release a short video on Instagram, Tiktok, and Youtube.

A new sharpie cap to make your markers more exciting! I provided a 3mf since this one benefits from a single tree support under the arch, however I did print one without support.
