Turntable of basic cable spool. (The misalignment of the edges of the spool was corrected later on, with some minor UV adjustments.)
The same turntable video, in red/cyan anaglyphic 3D... if you've got the glasses for it.
I'm the one consistent worker on a game project right now, amounting to a cosmic-horror themed survival game. Obviously I needed to worry about a number of tools, and the cable system has been important from a design standpoint, so here's my early draft of a cable spool and associated cutters for it.
I've also made your basic essentials (pickaxe-for-some-reason, hammer, screw driver, wrench, hatchet, tire iron, obligatory crowbar, and so on), but there's little reason to focus on them here and I suspect they'll change quite a bit in the future.
