The first of a series of molds to be made with a makerbot to make chocolate polyhedra. Modified to lay down so there are no overhangs during build. Makes an Icosahedron 3 cm from corner to corner.


Make five of these. The upper central edge running along the axis should be sanded slightly, enough to fit the syringe full of chocolate. Updated with a small square hole that can be used to fit a 3mm rare earth magnet set in with a bit of cut surgical tube (technique developed by Jeff Rutzky).

I see from the one Bre made that it should be modified slightly to lay on the vertical back for the build to avoid the overhang completly. I'll make another backwards compatible version that is hollow soon.

I did make a two part hollow version as well. The reason I made this five part mold was because the seams would be symmetrical along the edges with no seam cutting through a face.

One thing you might try is just making one with a hole in the top in the shape of one of the faces-- this mold wouldn't have the same injected precision on the upward-facing face, but it'd be a bit easier to fill and a bit easier to print...

Nice job. However,hollow molding might be easier:
assemble the mould apart from 1:
add a spoonful of chocolate
close the mould

A whole new landscape of possibilities opens up!

Thanks :-)

By the way, we need a script that makes a mold like this for any convex shape...

concave, too!

Difficulty rating-- nine out of ten.


This is awesome! I'm going to print 5 of these ASAP! Hmm, must get chocolate too!
