Adafruit 7" Portable HDMI Monitor Case Remix for use as a larger

Summary I remixed the case for the Adafruit 7" HDMI Touch Enabled Monitor, utilizing a spare camera LiPo. Adafruit offers a 5" version that runs off a camera LiPo and a 7" version powered by its own battery pack. This modified case combines the best features of both projects with fine-grained control over backlight brightness. Print Settings Printer Brand: LulzBot Printer: TAZ 6 Rafts: No Supports: No Resolution: Standard Infill: 20% Notes: The print was done with a brim to minimize warping. Translucent blue PLA was used to showcase the electronics and self-built nature of this project. Printed supports because the power switch holder is higher than the other switches, preventing it from drooping. Supports were easily removed and worked out great. Post-Printing Removed the brim and any remaining supports. Design Process Using battery holder dimensions from the STLs for the 5" screen, I modified a version of the 7" case to have the same holes for the Canon LP-E6 battery holder and a hole for wires to pass through. I doubled the thickness of the case back as the original 7" back was too thin/flexible for my liking. The added stiffness helps keep the battery holder securely fastened. The screw stand-offs for the PowerBoost board were deleted since they are not needed for this remix. Case Top Enhancements Two additional switch holders were added to control each of the hacker points: 50mA, 50mA, and 25mA separately. A large hole was removed from the PowerBoost and another switch holder was added so I could turn on/off power from the side where all cabling is located.
