Funnel for 500g Resin Bottle

thingiverse

This compact spout is designed to sit atop a 500g photopolymer resin bottle, providing assistance when pouring leftover resin back into the container. It features a double lip at the base, ensuring a secure fit and preventing liquid resin from dripping onto the outer threads of the bottle. A filter can be inserted inside the spout's top to remove particulates from the resin. This design is tailored specifically for 500g Elegoo Mars resin bottles, which have an outer diameter of 35mm at the opening and an inner diameter of approximately 28mm. Results may vary when using different bottle sizes or those manufactured by other companies. When printing this spout upside down (bottle rim facing upwards) with a FDM printer, no supports should be required. However, I have not attempted printing this in resin, so take the usual precautions regarding printing angle and supports. Edit 9/18/20: The STL file has been updated to feature a slightly thicker funnel lip.
