Bộ chuyển đổi nắp chai dầu 5 Quart

I usually buy 5 quart bottles of oil and they have a larger screw top than the old 1 quart bottles. Even some of the 1 quart bottles have gone to the larger top.  Mobile 1 and perhaps other brands have an even larger top.  So as re-mixes, here is a typical 5 quart to 5 quart adapter, and a Mobile 1 to typical 5 quart adapter.  I hope someone finds them useful. 

I printed with PLA and used supports on build plate only with the settings in the attached picture.  The supports were pretty easy to remove.  It might print fine without supports and with PETG.
