We never have enough cubicle hooks at work, so here's a parametric version.
The openscad file is composed of two parts: the base hook itself, and whatever you want to build onto it. The piece as-designed is to hold some headphones.
Print; cleanup; use!
[2011-07-28] Added "cubical_hook_with_loop"; this has a hook at the bottom to hang the headphone cable on.
[2012-08-02] Added "newcube_hook"; we have some new cubicles, so time for a new hook.
