X96 Max Plus - fan-ventilated box

If you own this Android TV box, you probably get stuck while playing video, especially in summer. This is caused by overheating of the electronics inside. The processor temperature rises above 80°C without any problem! That's why I designed this modification in the form of a new box with ventilation holes, a position for a fan and an added space for installing aluminum coolers for CPU and memory chips. This keeps the CPU temperature about 30°C lower! To prevent dust from entering the device, there are filter grids with a fineness of 0.6 mm at the top and bottom.

• FAN
  In my case, I used an 80x80x10mm fan, DC 5V connected in series with a KSD9700 thermostat, which closes its contact when the temperature reaches 40°C and thus connects the fan to the power supply. You can of course use the thermostat for a different temperature.
  Since I used 5V directly from the TV box power connector to power the fan, the fan would run continuously without using the thermostat. In addition to the thermostat, I also connected a 10 Ohm resistor in series to reduce the fan speed due to noise.
  If you don't have the possibility to solder wires or don't want to do this modification for some reason, there is also the option of using a fan with a USB A connector and plugging it into one of the USB ports. In this case, print "bottom_cover_USB.stl", which has a hole to pull the cable out.

• FRONT PANEL
  The front panel is designed so that the display can be read through it when using translucent filament. The filament PET-G Devil Design Dark Steel has worked for me. Nebula Chameleon Black also works.
  I also recommend setting the same direction of the print lines when printing, which leads to better readability of the display. In Cura slicer, it is the "Top/Bottom Line Directions" setting and you need to set it to 90° and turn the front panel so that the lines are horizontal to the display.
  The part in front of the display is 0.24 mm thick, so I recommend printing this part with a layer height of 0.12 mm.
  In case you don't have translucent filament, you can use the file with the cutout for the display "front_panel_open.stl" and insert some foil from the inside.

The remaining parts can be printed with a layer height of 0.2 mm and no supports are needed. But I recommend turning on Bridge Settings because of the holes for the connectors.

• MATERIAL FOR ASSEMBLY
  4x M3x10 flat head screw
  4x M3 nut
  4x rubber self-adhesive lens with a diameter of 8 mm

• COOLERS FOR THE BOTTOM SIDE (where the CPU is)
  4x aluminum heatsink 10x10x10 mm with self-adhesive tape
  1x aluminum heatsink 15x15x10 mm with self-adhesive tape
  or
  1x aluminum cooler 20x20x10 mm with self-adhesive tape - ATTENTION!!! - a cut is needed for the SMD capacitor, which is slightly higher than the CPU! (see photo)

• TOP SIDE COOLERS
  5x aluminum heatsink 8.8x8.8x5 mm with self-adhesive tape
