I looked at a lot of the models of the Plumbus out there and decided that they were either too hard to print (without supports) or the quality just wasn't there. I have been practicing my cad skills, so this is what I came up with.. Granted that this is very easy to print, but gluing is involved.. I made it in several parts so that you can print everything flat to the bed. It requires 2 colors of filament (or spray paint) or 3 if you print the stand. I printed this in PLA with .3 layers on an Anet A8.
Print the grumbo with dinglebop and the grodus in skin color PLA and the chumbles and floob in pink. I printed the stand with glow in the dark blue which is white till you turn off the lights.
For Scale the Grumbo is approx 4" in diameter(102mm) so this is not a tiny Plumbus
cheap generic Ebay PLA
Skin, Pink and White (glow in the dark blue)
I printed the Grodus and Grumbo with Dinglebop together, and the Floob and Chumbles together.
To assemble the Chumbles, after printing break them apart and put them in the small disk with the grooves in it, then glue them together. Then insert the disk into the Grumbo and put more Chumbles around the disk. then drop some glue in the hole to keep everything together. After the glue sets, bend the Chumbles away from the center. I included 2 sizes of Chumbles, you choose which ones you want to use.
To assemble the Floob and Grodus, align the 2 parts of the Floob and glue together, then glue the Grodus into the hole in the Floob. Glue the Grodus to the Grumbo and then you are done! you have your very own Plumbus!
I used 3dGloop to glue this together, but super glue would work as well...
