This small funnel is made to sit on top of a 500g photopolymer resin bottle to assist with pouring unused resin back into the bottle. It has a double rim at the bottom to help it sit more securely and keep liquid resin from leaking onto the outer threads of the bottle. A filter can sit inside the top of the funnel to strain the resin of any particulates.
This was made specifically to fit 500g Elegoo Mars resin bottles, which at the opening have an outer diameter of 35mm and inner diameter of about 28mm. For other sizes of bottles and/or from other manufacturers, YMMV.
When printed upside down (bottle rim facing up) with an FDM printer, no supports should be necessary. I have not attempted printing this in resin, so take the usual precautions there as far as printing angle and supports.
Edit 9/18/20: Updated STL with slightly thicker funnel rim.
