plotclock 3D printed parts

Now part of the plotclock kit available from : www.kghjfg.moonfruit.com

These are slightly different versions of Part3, Part9, Part10 and Part12 of the plotclock, changed for a 3D printer.

Originally Part3 and Part9 needed Part6 and Part4 to work, as the design was for a laser cutter not a printer. Now they print with the extra thickness where needed.

Part10 and Part12 are the servo arms. They now have a 5mm hole/socket so they fit straight onto the servos
