Amerimax k-style rain gutter cap

Could not find this type of cap, so I did a quick and dirty design on my own

I simply cut a piece of the gutter, scanned to jpg in my Xerox, then converted to svg for some tidying up in Tinkercad.

I used Flex Seal, but you can also caulk it to be water tight.

As usual, just mirror the model to get a cap for the opposite end.
