Printed in PLA on a Replicator using Makerware and default "low" resolution (fast) settings; extruder 205 deg C, 100mm/s extrusion, 10% infill. Coloured with a red Sharpie.

I managed to break one of the two inner-most pegs, but a bit of filament pushed into the cavity behind the peg soon fixed it ;-)
