"Button" pops up...

During the "proof of design" some problems with the Button have popped up. Take a look at the picture of the first one made. What design recommendations you would make to improve it?

You may want to look at the 3 view Orthographic blueprint for the button in the earlier Feb 17th blog  post - Things You Should Have Learned In School...  

In the picture below you can see the Sliding Compound Miter Saw being used to cut the 45 degree angle on the ends of the button. I will be taking the raw material and new blueprint to the students tomorrow for them to begin work making the Buttons. 

Puzzler - What steps would you do to cut out the buttons? What machines and tools would you suggest be used in the process?
