I love me some Calvin and Hobbes and really anything Bill Watterson touches. I wanted to show my appreciation a little bit too. So here is a Spaceman Spiff spaceship. I've divided it up into pieces organized for a bed smaller than 4.75" (120mm) cubed as well. If you have the bed space you can print is all together. The canopy obviously would have to be printed, sanded to smooth and then cast and molded in a resin.

100 for the ship hull. I would do 10-15% for the chair.
I used Solidworks to design the entire ship and to separate it for 3D printing set-up. I then used slicr to organize the pieces for a smaller bed.
