Hoberman Sphere

This is a simple approach, just be careful when positioning the parts on the printer bed.
The pin connector has a little support that'll need removal.
I've tried to design the parts so they'd fit right off the printer. Depending on the tolerances you have, they might be too tight. If that is the case, let me know, by printing two joining parts and trying this out, so I can modify the files. They work on my printer.

I'm currently working on a larger sphere, with diagonal lines as well.

It will require patience during assembly. .
Have fun making this thingie! :D
