Flatpack Sphere

Description

A simple sphere with 5 planes in 2 directions... Hand made in illustrator.

Can anyone recommend me a tool (commercial or free, but I prefer free :-) that will allow me to make planar cuts through organic shapes to be able to build them via laser cutter? For instance plug-ins for Blender or likewise. And pardon me if it already exists in Blender, I've only just started kicking around in it...

Just thinking, there has to be an easier way than keeping track of 3 planes in my head and hand drawing everything in Illustrator?

Cool! I'll look into that.

Thanx!

Google sketchup will let you do that. You want the "intersect with model" option. Draw your arbitrary shape using the usual tools. Then draw how ever may planes you want in whichever direction. Make each place a separate component. Then for each one edit the component, select one face and Intersect with model.

You'll get the lines of your aribrary 3d shape on each plane. Then you can push-pull into whatever thickness material you'd like. If you have planes in multiple directions, after this is where you'd intersect a face of each pulled out plane to model the slots and tabs, etc.

That's essentially how I made the plywood chess set.

Instructions

Cut one copy of the outer circles, and 2 copies of the inner circle file. The rest is pretty forward (although I recommend a touch of glue or a more snug fit than what I have made). Optimised for 3mm materials...

I've only made this in HDF so far, but I'd love to see what it looks like in colored acrylic!

(Better picture coming soon!)

EDIT: Better picture has arrived.
