About this 3D model

Careful : This is a work in progress !i haven't printed it yet. This said, i couldn't stop with this for my daughter :http://www.thingiverse.com/thing:312671 "Dad can you make a bird nest for me with the 3D printer ?" "OF COURSE I CAN !!" ;)). So i had to make a bird nest ! But i also wanted something special otherwise there is a ton of excellent designs already... I wanted the kids to be able to watch what happens in the nest on daily life (maybe even install a webcam..) so... My objective is to make a 3D printable nest that can be attached to a window glass, making bird observation in the nest possible ! I'm not yet pleased with the design (too thick/heavy, too much filament). But i'd like comments from you guys (and girls !) to make it better. Let me know what you think... (see instructions for print & questions)
