Bird Feeder micro 3D print model

This is a bird feeder for smaller birds. Just put in some bird seed and it is ready to go. Bigger birds can not get to the food, because there is noting for them to hold on. If they do, they can fly hanging still in mid air. I have seen some crows do it ;-). The design is inspired by the way trees hold up their branches and leaves. But is still has the classic bird feeder form overall.

At 129mm high and 60mm in diameter, this bird feeder is really small. Normally I design bigger bird feeders, but they also take a lot more time and filament to print. The print duration is 3,5 hours and it takes 32gram of filament to print with the print settings of:

0.2mm resolution 4 wall lines 4 top/bottom layers 15% infill

The parts should click together like Lego (and I did not even need glue)

Do you think I forgot to tell something and still have questions? Feel free to ask :-). Do you think I made a mistake or could have done something better? Feel free to give some constructive comments :-)

PS: the OBJ & 3MF file are a assembly of the lose STL file parts
