I made some sunglasses because it's summer.
There are two versions available:
This one is intended to be printed in one piece including the hinges. It actually works very well but the frame is a bit fragile and looks a bit rough with some materials when printed in this orientation. Pro-tip: print it upside down! It'll use much less support material this way.
prints in one piece
support removal can become critical to the structural integrity of the frame
looks less awesome
This comes in three pieces which can be tucked together afterwards very easily.
much nicer finish on the front face
groves for the glasses come out more precise
side pieces can be printed in different colours/materials
it's possible to disassamble the glasses
you can get rid of the lettering easily
support removal more easy with almost no visible residues
a bit more wobbly side pieces (but they're both quite wobbly to be honest)
I haven't put in real glasses/lenses yet; have to find some cheap ones to get them cut into the right shape.
The picture I've attached is from version #48 btw.

print it upside down with plenty of support for angles > 40° and 100% part cooling. Removal of support is a pretty unpleasant experience and you can destroy the frame quite easily while doing that.
the frame comes in optimum printing orientation while the side pieces can be printed either the given way or upside down. The latter uses less support material but comes with the chance of worse overhangs. However I recommend support for angles > 40° anyway for the side pieces. The main-frame comes out good with support for angles > 70°. If you don't want the silly signature on the side frame, just mirror the "bruen48_buegl_r.stl" which is a blank one. Part cooling @ 100% recommended for all parts.
BTW: The frame on the picture was made with yellow PETG and black "green-tec", both from Extrudr.
