About this 3D model

A 3-piece egg shaped birdhouse with built in rain catcher (1 degree tilt) filling two water bowls, a canopy, inner to outer extending perch, with m4 holes for an interior roosting perch, a drainage hole, and hanging loop. Diameter excluding the rain catcher is 150mm. The door hole is 40mm in diameter. Requires: 4x m3 10mm screws (1 for the perch, 3 for the top and bottom halves) a stick, skewer or rod that's 4mm or less in diameter (for the roosting perch) - you could edit the SCAD file to make the holes larger (I have not test printed any of these parts.... I did not account for all that weight in the front while designing, I will figure something out for that, but for now, perhaps a counter weight would do the trick) Which came first: the birdhouse or the egghouse? Update: I've finally printed one out, the walls are a tad too thin, the birdbaths may leak, but some glue or filler would take care of it. Printed: 3mm layers, 20% infill, no support, no raft
