Debra Ansell of [GeekMomProjects] fame came up with a neat, 3D design that prints flat and then folds up into everyone’s favorite Platonic solid: a D12.
Why would you want to do this? Well, folding up your 3D prints gives you a third dimension “for free” without using all that support material. Here, all of the outside faces of the dodecahedron are printed flat against the build plate, which is probably the nicest side of your prints. And embedding LEDs in the resulting shape would probably be easy because they’re all in plane. And speaking of LEDs, we kinda expected to see them here, given Debra’s motto: “LEDs improve everything” — that part is up to you.
Debra notes that she likes PETG instead of PLA for the extra strength in the thin-printed hinges, and we’d bet that your printer’s tolerances will need to be spot on for the clips that hold the whole thing together. (We’d be tempted to apply a little super-duper glue.)
As always with Debra’s projects, there’s some creative solutions on display here that’ll help you out whether you need a D12 or a D20, so give it a look!
Thanks [Peter] for the tip.
Now I’m envisioning using a tool like Pepakura Designer to convert a 3d model to a papercraft net, and then transforming that into a model like this.
Pepakura is so under rated !
Amazing program.
I am still looking for a user manual in English.

The ironic part is that 3d printing was supposed to overcome the need for assembly like this. This design is suited for injection molding but seems antithetical to 3d printing where you should be able to simply print the dodecahedron. The benefit of folding parts like this is that you need not worry about things like scaffolding.
All this aside, a more reliable design might be single side that has intermeshing/interlocking edges. Just print 12 and slide them together to get your dodecahedron. Then you could print different shapes and make some sort of lego-esq set.
You’ve got it backwards…
Perhaps there is a compromise with fewer snaps to hold it together as it is assembled, speeding the assembly process is that is important. I like it in that an object like a ball of a different color can be placed inside before it is completed. Or really any object that can fit that space. And I presume it is scalable.
Don’t send it to iFixit…
