Chrysler Jeep Dodge Ram no spill thread in oil funnel with quick drain

This 3D model is a custom oil funnel designed for easy printing without supports. Perfect for vehicle maintenance. I Made this for an oil shop about 6 months ago and it has been dropped and used heavily, but it is still in great shape. I also put a place for a rubber o-ring shown in photos.

Suggested Print Settings:

Orientation: Top rim on build plate opposite of pictures Material: PETG (Elegoo Rapid PETG), ABS, or stronger materials like nylon. Printer: Creality K1C or similar. Layer Height: 0.2mm Infill: 100% Brim: optional
