7x7x9 cuboid extensions

These are extensions for a Shengshou 9x9 in order to make a 7x7x9. Print the file twice and glue them to opposite sides of the cube. Credit to Casey Weaver (TwistyTex) for the inspiration with his 5x5x7, first 7x7x9 created by Ola Jansson in 2010.

I've included a 'sharp' file as well in case you don't want such rounded edges, and also the *.DXF files for the sticker templates if you have a sticker cutter at home.
