Screw-on motorcycle oil funnel - print in place

Screw-on funnel for the oil filler port on my YZF-R6. The funnel rotates independently of the locking nut and locks into place when the nut is tightened. Print in place. 

The thread size is M27x3 - a common thread size for oil filler caps/crankcase caps on motorcycles. You can test print the screw by removing the funnel part on your slicer. You can also test using a plastic bottle. The threads on the common plastic bottle for soda/pop or bottled water is the same size as the oil filler cap - if you can screw in a plastic bottle to your oil filler port, this model should fit. 

Print with the threaded portion on the print bed. I used brims on the insides mainly to keep the funnel in place. Supports will be necessary for the hand grip/knob. I added a little line of support on the underside and halfway up the funnel just for peace of mind. The gap between the funnel and the inside of the screw is only .2mm - you may have difficulties printing if your printer is not well tuned.
