This is a DIY suncatcher. WARNING, IT'S NOT COMPLETE IF YOU JUST GET THIS PART, YOU HAVE TO ADD THE TRANSPARENT BITS YOURSELF.
To make it you need this part here, plus 12 panes that you cut out of acetate or some other transparent sheet stuff. Full instructions and download files for the panes are at
Thingiverse.
No markup on this, it's just for fun.
