Summary

I Saw a few similar ones on here for flies, but our problem here is wasps, i also adapted it to be able to have a string run through it so it could be hung from a tree...

EDIT: I just added V2, i found V1 did work, but it wasn't a smooth and a little tighter on the jar than i wanted. I recently learned how to do threads, so i recreated it entirely around the threads i found worked well on the jar, so V2 is a complete rebuild from the threads out, i think it fits a lot better.

EDIT again: I made a V3, i thought the cone in V2 was too thick, so i narrowed it in V3, takes like 3.5M less filament and almost an hour less print time now at 100% fill

And again: i dont know how to leave things alone, this is V4, i made it with little handles on the outside instead of the holes in the previous version which would allow the liquid to leak out the threads if it was tipped over, i am sure this one wont be leakproof, but it should be a lot better.
