I used the beautiful lock for my chest, thank you for this excellent idea.
At http://dragonpowered.co.uk I found still simple, but great hinges.
I have experimented with the engravings. Wood grain, nails and a viking ornament.
The ornament and the wood grain (pictures) i have not integrated in the DXF, but you kann download them.
Now my Viking Treasure chest is complete.
The material is 4mm beech plywood
