Raspberry Pi 7" Touchscreen - Rollbar and Skidplate - Now With Sound - Adafruit Speaker Bonnet + Pi 4 Version

thingiverse

Previous version here --> https://www.thingiverse.com/thing:3771857 This is yet another update to my Rollbar case for the Raspberry Pi 7" Touchscreeen. The changes include: Addition of mounting bosses for Adafruit 3070 (4ohm, 3w) speakers on the back of the rollbars. Removed the 45 degree viewing angle option and changed it to a 75 degree viewing angle - as the 45 degree angle was too shallow to be any use and changing the angle facilitated mounting of the speakers. There are speaker grills that match the Adafruit speakers. The are some provisions to make the center cover stay in place better - saw too shaped protrusions on the roll bar parts engage corresponding cutouts on the center panel and prevent it from moving out of place. There is a Pi 4 version of the box on the back. Other than the roll bar parts not fitting with the old center section, everything in this version is basically compatible with the older versions. You can use the old Pi3 box with the new roll bars and center section. Or the old lid with the fan cutout. These are the speaker intended to be used with this system. https://www.adafruit.com/product/1669 If you use these with an Adafruit Speaker Bonnet, they have connectors so no soldering in required. I suggest using some m3 screws that are 8-12mm long to mount the speakers. The (also m3) screws that hold the whole thing together are much shorter - like no longer than 8mm or else you risk bottom them out on something inside the screen housing. Look carefully at the Speaker Grill part. The whole item is 2mm thick, but the little support pieces that hold the inner ovals is only 1mm thick, so with a pause at 1mm layer height you can change from your primary color to black to make the inner ovals look like they are floating (if you're not printing the whole thing in black). I will write more about this and maybe add a few more parts - like more cosmetically pleasing version of the skip plate for a Pi3. But I wanted to upload this quickly to give this option to a user that was asking about my previous version. As with all my previous versions, this prints fine with no support. There is no support needed on the Rollbar parts, the Skinplate case around the Pi has some small holes for the various ports which might benefit from support, but are so short it isn't really necessary. And the center cover has some similar sort bridges that might benefit from support, but it's not necessary.
