I took pieces of the cardboard from the package that the printer came in and fixed them to both sides, also made a door that fixes it self with a magnet and a steel handle which the magnet draws. i also made a lid that just lies loose on top of the machine.

I made this adjustable endstop for the Z-axis, i know that there is more of these out there by now. i made this to accommodate the length of both my j-head and E3D head. http://www.thingiverse.com/thing:146437
