This case is designed around this screen and not the one that is recommended. http://www.amazon.com/SainSmart-Arduino-Mega2560-Raspberry-Display/dp/B00J9AAZMK/ref=cm_cr_pr_product_top?&ie=UTF8
I used this one because of accessibility, I was able to get it at a shop near by me. If you want a case for the old screen, try my original case. http://www.thingiverse.com/thing:241814
I have included side panels that have no holes so that you can cut and drill your own connectors.
Links to the screws, nuts and other parts I used and designed for are in the instructions tab. I will add assembly instructions soon, I'm still testing.
