A remix of Ant Moat Repaired Flat by Intrglctcrevfnk https://www.thingiverse.com/thing:2490992
I found that they would leak sometimes and the pesky little ants figured out that the smallest of their clan could make it through the hole next to the wire. Also it wouldn't actually lay flat on the print bed which was obvious when slicing with a skirt in S3D.
Made 3 sizes of holes which is in the file names 2.6, 3 and 4mm's
Made a loft and round base to make them more watertight it also makes it possible to stand them up on their bases
Sliced the model so it has a real flat surface to place on the bed
In the pictures the green is PLA and the blue is PETG
Used 4 top and perimeter layers with 3 bottom. Top is actually the bottom of the moat when printing so it's actually 4 bottom layers when done.
