these have yet to be printed... I have the .stl files for them. i just need to load them into the printer and hit GO........ The .stl files came from thingiverse and can be modified to your liking or kept as is.. i plan to make a solid print that will have a base with the above and tanks.. I have an ant nest making business, but plan to do this as a side project https://www.thingiverse.com/antbizzo/designs
oh and the sizes are 2-4 inches
