This is a wasp trap, It is more compact than its previous version (https://www.thingiverse.com/thing:4263483).

Lid compatibility : Twist-Off TO 63

• The cap diameter is 63mm (inside),
• The screwing part contains 4 edges evenly space 3 mm apart (12mm for a single helix).

Features:

• easy opening (screw on regular jar),
• a hole on top to let a string pass,
• protections prevent rain water to fill the trap.

Important note: the color of the filament seems to have a strong impact on the trap efficiency. I dont know anything about the visual spectrum of the wasp, but from my experience, Orange PLA worked better than black NGen. Please let me know if you tried other materials / colors.
