this is a germ. it could look like a different thing than this, or it can be the same.
Step 1: The Center
Take a look at the picture (if you can). if you can match it up as good as you can then this will work out just fine.
Step 2: The Edges
Follow what the picture says. if you get the sizes correct, then you can finish this up.
Step 3: Adding the Edges
you can add the edges any way you want! you can adjust this in any way you can.
Step 4: Finished!
now that you are done, you can 3D print this project and show it off! sorry if this was not exciting... I tried.
