Decided to make a woodland's themed baby mobile for some work friends.
The acorn is a remix from dmbone's thing (https://www.thingiverse.com/thing:1882427), and the swallow is a remix from tokehs' thing (https://www.thingiverse.com/thing:1882427), but tokehs does not allow official remixes so you won't find an STL for it included in my post (sorry).
My make was painted using a small air brush and water-based acrylic paints. Nothing special required, just some time and patience.
Additional Components Needed
2x 11mm wooden dowel rods
several feet of fishing line
