Bird fat ball roof

My wife want have a roof for bird fat balls.

I made it with TINKERCAD.

The support you need is included! Don't print any rafts! If you do, the hook inside the roof will break up. It not possible to remove the inner hook from the heatbed if you use rafts.
The thickness of the roof is 0.8mm. No infill is needed. I print only two lines with 0.4mm nozzle and it works fine.

Have fun with it!
