Under desk cable catcher/holder

Under desk, chair side cable catcher/holder inspired by http://www.thingiverse.com/thing:3706. Got tired of fishing for the right hanging cable. Comes in two sizes; for heavier charging cables, and for lighter cables like on a wired mouse. Extra cable length can dangle underneath. Pull the cable through to use, or detach from holder.

Photo 1 shows print for large cables on left, and small on right
photo 2 shows them installed (in the other order) on my rustic chair side workspace.
