After having found a Asian Hornet nest in my backyard, I decided to look for a trap solution. That is when I found the model from BartG40. However, since I wanted to make use of some plastic bottles I had around the house, I decided to adapt his original flat model to have a curvature that would fit said bottles. You can then hang the bottle from a tree branch or place in hanging from a ceiling if you have an outdoor covered area.
I recommend you check BartG40 model, listed below, for more details on the Asian Hornets catching procedures and information since its very insightful and useful. This trap also seemed to catch regular wasps and flies.
For this current model I printed it in PLA, with the smaller hole making contact with the heatbed, which naturally requires you to use supporting material for the upper part. You are of course free to print it in another manner, and use a more durable material, but this was what I used at the time.
The author remixed this model.
Model adapted for use with plastic bottles.
