5 gallon bucket lid spacer

I use mosquito dunks as part of my pest control.  I drop them in 5 gallon buckets.  When it would rain, they would eventually over flow or if it didn't rain for a long time they would dry out.  I wanted to cover them with the lids but have space for mosquitos to still come and go.  I also live in a super windy place so I needed the lids to be secured.  I've used various brands of buckets.

One warning, once these are attached to the lid, it is difficult to remove without breaking the part or the lid.  I've used these for one season and had good results.  One set ended up breaking for some reason but the other three stood up under the elements.  I printed the pictured models in PETG but I need to replace my broken ones so they are getting printed in ASA.

Hope this helps someone else.
