I've been intreated by the idea of 3D Printed "Stained Glass" for a while, and after LOTS of experimenting I came up with this.
Yorkshire Rose: Thats where I live ... :-)
The frame is printed in 2 colours, first half in clear then with black for the bits around the colour areas.
When the bits were printed I then glued them into their areas using PVA glue - it dries clear .. but it took around 5 days for it to finally clear.
All Rigid Ink PLA, colours used: Translucent Green, Natural, Pearl, Yellow, Black.
