Subject: led-clip: an clip to mount strips of leds to surfaces
X-Git-Url: http://git.hcoop.net/clinton/3d-models.git/commitdiff_plain/12c98db537b6394ce6dff6893269f92be57080b1

led-clip: an clip to mount strips of leds to surfaces

Written in 2015 and just sitting in a folder since, which is my excuse
for the awkward math.

Inspired by some long-forgotten model I found on thingiverse... it
wasn't parametric so it couldn't fit waterproof strips, inspiring this
quick hack.
