Pie case With lcd and buttons

WIP
raspberry pie case inspired by Stargrove1's Raspberry Pi Music Player housing with LCD. I liked the Idea but wanted more functionality so I designed this case to have buttons along with the LCD.
the lcd is a cheap 16x2 from dx.com and the buttons are 6mm tacks.
this has yet to be printed so files may change in the near future.
any advice or suggestions are welcome.
