Small bird feeder
Print in its normal orientation - with the drain holes and bottom on the bed. Printed at basic settings for quickest print with no support needed. Then I spray painted them in bright colors. They attach to the windows using some suction cups I had from another project. I have also hung them from a screw into one of the poles supporting the patio roof. I just tightened it so the screw head held the feeder tight against the pole or you could use a washer to span the hole in the feeder. All the birds use them from little buntings and cardinals up to grackles and blue jays.
