End cap for my window blinds

This is a plastic piece that is part of the system that holds my bathroom blinds up. This piece was missing from one side, so the blinds kept falling down.

The model contains a small support on each side that must be removed after printing.
I successfully made this with ABS, 0.2 layer height, no raft or supports, and the popular 230/110 extruder and build plate temps.
