Case for piCorePlayer + Waveshare 7.9 inch display

This is my case for a Pi3 based piCorePlayer using a Waveshare 7.9" touch screen and a HifiBery DIGI2 Pro HAT for music output. Focus was on flexibility of the case and not to make do with as little filament as possible. I wanted all necessary connectors (including the SD-Card) to be easily accessible. Due to that some more cables are required so that everything can be placed accordingly inside the case. For flexibilty reasons there are four sockets for keystone modules so that one can easily modify for custom use cases (for example a 12V trigger output). You'll need various 90° or 180° adapters for HDMI, USB-c and micro-USB to make all cable connections in the given space. Due to the keystone modules you are pretty free to decide how you want to do it.

Part p3 has hollowed out walls to accomodate some lead weights, so that the case wouldn't move placed on a slick surface when operating the touch screen. I've used these weights, but they're optional, you can do without them.

I didn't make any provision for feet on purpose. I've used some adhesive rubber feet.

How to assemble it:

1. Attach the HDMI cable to the display using a 180° adapter.
2. Print part p1 and mount the display to it using four M2.5x10 screws.
3. Attach the remaining cables (touch, power) to the display.
4. Print part p2 and put it on part p1, feed the cables through and mount part p2 to part p1 using six countersunk allen key M4x12 screws.
5. Print part p3 and put it on part p2, feed the cables through and mount part p3 to part p2 using six countersunk allen key M4x12 screws.
6. Print part p5.
7. Connect the HifiBerry DIGI2 Pro HAT to the Pi3 using a ribbon cable.
8. Mount the DIGI2 Pro HAT upside-down on the left side of part p3 using M2.5x10 screws.
9. Mount the Pi3 on the right side of part p3 using M2.5x10 screws.
10. Connect the cables from the display to the Pi3.
11. Connect the power cable to the Pi3 and a keystone module on the other side.
12. Connect the other cables you want/require to the Pi3 and respective keystone modules.
13. Print parts p4, p4a and p4b.
14. Slide part p5 into part p3.
15. Plug parts p4a and p4b into the backside of part p4.
16. Put all keystone modules into part p4. Leftmost socket is for power.
17. Mount part p4 to part p3 using four countersunk allen key M4x12 screws.

Enjoy!
