The file 'Birdhouse 3D Printer Model' is (stl) file type, size is 3.9MB.
The opening is 4cm, it took me about a day (24h) of printing and 500g of material (2 walls at .8mm nozzle and 17 % infill). You'll need a 200mmx200mm print bed.
I designed this to be printed without any supports, but some parts are tricky. If you dont have my aversion, you should probably support the left and right holder-parts. It did work out for me with a .05 layer-hight with lots of fan and 30mm/s. The bridges also need attention (entrance-part as well as in the roof): full fan and slowed speed worked for me.
The brace is to be printed in vase-mode. You dont really need it though, if you are willing to use glue.
FYI: I now tried both arm-versions and I find the first one far more easier to assemble at the tree and it seems more stable. Version 2 should've allowed to better bring the house in a leveled orientation (no fixed positions as in v.1) but the house kept tilting before I could fix the screws .. finally the outer half ring of the handle snaped :( ..
