I honestly can’t remember where I got the idea to make a bunch of dodecahedrons for Maker Faire Milwaukee came from, but I do remember looking at Thingiverse for some connectors I could use with 1/4″ dowel rods. I know I tried Trammell Hudson’s design, since I always admire his work, but I was not using pencils, so it didn’t work. I did attempt to alter his file, but ultimately ended up designing my own file, which worked well enough that I wanted to share it. (Check out Dodecahedron Connectors on YouMagine.)


So I made nine dodecahedrons that could hang from the ceiling in the Dark Room. And since they’d be in the Dark Room I figured I should use fluorescent filament to create the connectors, and fluorescent paint to paint the wooden dowel rods, and with help from Kathy H. at Milwaukee Makerspace, we got everything painted. Sadly, we did not get the blacklights set up in the Dark Room due to budget constraints, and there was too much light where they were placed, and we had to bundle them all together, and… well, anyway, they turned out great, despite a few issues with presentation.


I’ve also made a smaller (hand-held) model for home. It’s small enough to fit on a 13″ MacBook Pro, though I might hang this one from the ceiling as well. Or maybe make it into a lampshade. I don’t know yet.


This is the original version, which uses 12″ long, 1/4″ diameter wooden dowel rods. A pack of 100 dowel rods is under $15, and a roll of fluorescent filament is about $22. Since you need 30 dowel rods and 20 connectors per dodecahedron you can easily build three large ones (or a lot of small ones) for under $40 USD as long as you’ve got access to a 3D printer.

Did I mention I really like dodecahedrons?
