To start here is the 2.5mm slot one that is good for sorting medium sized and larger mealworms.Įdited: added 1.5mm, 2.0mm and 3.0mm slot widthsĮdit: added same sizes as whole inserts for those with large enough print beds. But I will be adding other sizes for sorting mealworms by size. I will not be making one with the same slot size as the link above, It works great for pupae and you can get one from him. After purchasing a Pupae sifter insert from here ( ) I realized the slots are the way to go and as this was the only size being sold from this person I decide to fill the gap with my own inserts for the other sizes. They work good but the worms don't fall through the screen holes as well as they do slots.

I started a small mealworm farm and purchased a set of bucket sifters ( ).
