Faux stained glass-light catcher. Printed in ABS on an SD3 at .3mm. The frame prints upright, pieces print upside down... Frame prints upright, flip pieces over and insert into recesses in frame. I used some acetone on a brush to glue pieces into place. Note: I couldn't settle on a color for the top at the time I took the pics. you could just use the space to hang the model, although the piece is included.
