PolargraphSD v1.2 case
by euphy, published
This is a case for a Polarshield v1.1 or v1.2 with attached LCD, Arduino Mega and Stepsticks, as used in my PolargraphSD machines (www.polargraph.co.uk).
It is improved over the old version and more stable and uses less filament.
It fits the slightly modified Polarshield v1.1 (servo aperture moved a bit) and is designed for a Freaduino Mega with a mini-usb connector. It just takes a couple of chops to move the hole so a regular sized USB connector can go in it.
Requires 6x M3 12mm bolt and nuts to assemble. Use plain nuts instead of nylocks (if you're tempted): the hexagonal holes that lock them might not be strong enough to keep them from turning, and this device is not subject to vibration anyway.
This is made to fit the MEGA2560 boards I use which have mini-usb sockets on them. For this reason you may have to chop at it a little to get a regular Arduino with a USB-B socket on it to fit.
