I use the smart slot as the base and make it 5l 5w 2h.
Then use the shell function to hollow out the base.
Then put the smart keyhole on one side of the base and starch it so it is out the other side.
Use the subtract option under the combine function to cut the keyhole in the base.
Add text with the smart text. It can be change to whatever you like it to show.
Use the subtract option under the combine function to cut the words in the base.
Add a smart trapezoid on top of the base and change it to glass material.
You can change the base to other material also.
