This funnel comes along with two nozzles; a universal one, and a specific one for Anycubic uv resin bottles. You may want to print the filter template to cut your filter at the proper dimensions, its diameter is 36 mm.
The SCAD file is attached, you may want to adjust the tolerance value according your preference. Note that this file uses the ISOThread library from RevK and the polyround library from IrevDev.
0.6 mm tolerance thread as been added to download by default. A ZIP archive contains the original files with 0.3 mm tolerance which I printed for myself and that you can see on the photography attached. Please read the comments section if you would like to have further details about these updates.
I printed the nozzles with support material. The funnel (upper part) does not need any support.
I used the metal filter from an old strainer which I have cut to the proper dimension using the provided template.
