Printrbot Nozzle Adapter for Makerbot Printers
by Jerrill, published
If you own a Makerbot and want to get in on the action of using the Printrbot nozzles that you can make using the Printrbot Nozzle Fabrication Toolbox at http://www.thingiverse.com/thing:53316, then check this out.
You can drill a 3/32" inch hole in a M6x1.0 male to 1/4"-20 male brass thread adapter (McMaster-Carr P/N 97437A600 found at http://www.mcmaster.com/#97437A600) like I've done in the photos. If the hole at the M6 end is a little off-center then you can use a larger drill bit to bevel the edges of the hole. Most likely the hole being off-center at the other end won't matter since there is still plenty of a path for the molten plasting to get the hole in the nozzle.
