PolargraphSD acrylic case parts
The case is a set of 16 laser-cut acrylic parts that wrap a Polarshield, LCD and an Arduino MEGA-compatible board up.
It is the exact same parts as are fitted to fully built PolargraphSDs.
This item consists of the 16 parts cut from clear and opaque acrylic and nuts and bolts that go with it.
Instructions are here: https://github.com/euphy/polargraph/wiki/The-PolargraphSD-case but there'll be improvements to that page over time.
I have stock of these packs right now and am selling at more-or-less cost price.
