This is a fully modular snap-fit (no glue required) model of an Airship. It is the vanilla base for a series of absurd mashups that currently includes a Trireme and a Saturn V rocket. Designed for 3D print, it comes in two flavors: solid and shell. Both the shell and solid versions have been prototyped on a Replicator 2 with no supports (and no raft but that depends on your confidence with over/under-sticking). Sliced in skeinforge it works best at I had good results with the following settings in print-o-matic:no support/no raft layer thickness: .15mm (or less) Number of shells: 1 or 2 feed speed: 80mm/s travel speed: 150mm/s fill rate: 0 (for shell version) or .1 (for solid version)My actual slice profile is a little more complex but with print-o-matic those are the settings that will get you started. The shell version was designed to keep the material use to a minimum and works quite well but I think the solid might actually print faster at low rates of infill because there is less shell and perimeter to print even though they have been minimized in the shell version.The snap fit is pretty self-explanitory with the seperate H-clips intended to attach the two main halves together with the nose and tail cones snapping into the integrated snap prong features on the main body. The propellers just push into place. Print two and you can have a four engine Mega-Airship and a windowless drone ship! Or check out the Trireme and Saturn V upgrades to make a mega crazy super cool ultra futuristic ancient star ship.
