My hubby is very handy, will have to share this picture. Great job on the build!
Then a few more photos for ya. (Or for him)
Below you will see two collars that I added. For some reason just at those two ports a little feed was billed out... but not at the others. So for the two problem ports I added collars and just attached with duct tape so that they would be removable and adjustable. Worked great. People with heavy rodent problems buy the pipe caps, and cap the pipes every night, take them off every morning.
Some have glued an upside down funnel in the middle... to make sure the feed flows nicely to the ports... I didn't... and it feeds fine... pellets or crumble (no mash up here.. so I haven't tried that)
Pic below shows how high up the bottom of the tube is from the floor of the trashcan. Looks like 1 and 3/4 inches.
