Mason Jar lid wasp trap

thingiverse

I'm glad I can help! I didn't want to spend 15 bucks on a wasp trap either. So, I made one that fits perfectly around my mason jars, which are 66mm in diameter. I've also uploaded the 123d file so you can modify it if you need to. If you like this idea, be sure to give it a thumbs up! Simply print out the design, place some beer and sugar at the bottom of your jar, then use it just like your regular mason jar lid with the pointy side facing inwards - and that's it!
