I saw a great 123D Catch scan and wanted to make it 3D printable. I deleted the surroundings and made it solid, cut a flat base and added a hole in the back that supports a screw or nail so it can hang on the wall.
The model was scanned by Timofey Nikanorov in Saint - Petersburg, Russia.

The author marked this model as their own original creation. Imported from Thingiverse.
