Funnel and bottle base for Elegoo resin

thingiverse

I have designed a funnel that screws directly into the Elegoo resin bottle, eliminating the need for any additional support when refilling with excess resin using filters. Although the bottle did not appear prone to toppling over during refilling, I have also created an extended bottle base in the shape of a skirt that tightly fits within the bottle (as shown in the images). I have added an air intake channel, ensuring that even rapid pouring of resin does not produce bubbles and flows smoothly. With this design, you can leave unused resin containers on the funnel until the last drop of resin falls back into the bottle. Note: The pictures do not display a filter, but it is essential to use one with resin that has undergone the printing process. Note: Due to the shape of the upper lip, the fit on the bottle neck is quite snug. You need to press down about 1 cm before the spiral catches and you can securely screw the funnel onto the bottle neck. Note (added August 30, 2019): A base for 1L bottles has been added. The original design was intended for 0.5L bottles and is still available.
