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
