6x1.0x13mm Male to 10x1.0x8mm Female

This is an adapter to take you from the 6mm extruder to a 10mm bowden conduit fitting. This wasn't a permanent solution because I ordered the brass fittings but it was a quick fix because I didn't want to wait around for those fittings to come in from eBay! I cleaned up the threads a little with a die but it finer printer settings should get a print without post operations.
