This is a simple dragon design based on the Welsh Flag, which can be hung from a wall or anything else you'd like to decorate with it. It comprises a front and back piece, the back being pushed into the rear of the front and fixed in place with a little glue. There's also an infill piece which is inserted between the front and back before gluing, that allows the dragon to show through in a different colour.
I used translucent filament for my infill pieces, so when hung against a window light shines through and gives a nice effect. However, I've also included a back piece without cutouts which may be useful if you decide to use opaque materials. The holes at the top allow the plaque to be hung using some chain or ribbon. I've printed this in PETG and PLA, including gold PLA, and all came out OK.
