Quick Mill new drip tray drain plug adapter for old drain hose

thingiverse

I had a previously installed drain kit for my Quick Mill espresso machine, but needed to upgrade to the new drain style. I remixed this excellent design to add inner threads so it could be screwed on. I printed it in ABS due to the hot water it would be exposed to and found scaling it up by 2% accounted for ABS shrinkage, resulting in a perfect fit. I also used some teflon tape around the male threaded part of the drain for extra safety measures. Print with the female threaded part face down. If printing with ABS, turn on the fan to 20-30% once you get to the overhangs or they will sag and the print will fail. Update: I've been using this since September with no issues whatsoever.
