Inspiration

I am interested in robotic assembly of large scale structures. I am experimenting with making lattice structures that might lend themselves to robotic assembly.

What it does

This is a fastener that can connect two identical parts with a simple pull and twist motion

How I built it

Lots of time in TinkerCAD because I don't have space on my hard drive for CAD software. Will try Onshape next time.

Challenges I ran into

3D printing mechanical assemblies in one go on FDM printers won't work because gaps cannot be made between components without support material.

Accomplishments that I'm proud of

A good fit

What I learned

3D printing complicated assemblies takes a significant amount of development time

What's next for Quarter-Turn Androgynous Captive Mechanical Fastener

Continue development and integrate into my structure assembly
