Antproof Bowl
Description
This is a bowl I designed to keep ants out of my chicken feed. My chickens love mealworms, but the ants like them more. If I put them in a regular bowl I'll usually have 30-100 ants inside the dish within 15 minutes, and the chickens wont even bother eating. Add water to the base, and thread the top in and it'll create a moat of water that the ants can't swim accros. I tested this by putting it outside with some mealworms close to the ants. I left it for 3 hours and there were 2 ants in it, however they were stuck and just ran around in circles unable to find their trail back to the nest. I do not recommend using anything other than water as it could poison the animals. This was designed for my CR-10, however you can scale it down to 75% to fit the Ender 3. Photos are of 75% scaled down version, printed on Ender 3. Print the base oriented correctly (opening facing up) and the top oriented upside-down (opening on build plate) Ive printed with both a .4 nozzle, and a .8 both work well I used 20% infill, and just increased the top/bottom layer thickness, and wall thickness to create a better seal between layers. I used 4 layers for each setting. Printed with supports touching the baseplate at 50 degrees or higher so it only supports the bottom of the bowl. I then used needle nose pliers to pull the bits of support interface off of the bowl. I recommend PETG, and you should print at a slightly higher temp to ensure a good seal between layers so the water doesn't slowly leak out.
