This is a small case for Raspberry Pi, which supports UPS, cooling fan, memory card insertion and removal, and battery removal. The size is 92 * 92 * 60mm

If you want to make this case, you need to prepare the following materials, of course I also gave a list of materials:

Raspberry Pi 4B
1
Buy it yourself
Raspberry Pi cooling tower
1
Used for Raspberry Pi heat dissipation, horizontal fan can effectively save space
Raspberry Pi UPS PLUS

Don’t buy it wrong, buy this one under the Raspberry Pi
0.96 inch oled
1
Used to display
M2.5mm nut
4
For top fixing
M2 x 3mm hexagon socket screw
4
For 0.96 inch oled fixing
M2.5 x 8mm hexagon socket screws
12
Used to fix the side screen * 8 Used to fix the bottom acrylic * 4 It can also be used to fix M2.5 * 14 copper pillars * 2
M2.5 x 6 + 6mm copper pillar
4
For the cooling tower of the Raspberry Pi, you can use the built-in screws
M2.5 x 7 + 6mm copper pillar
4
For UPS for Raspberry Pi, you can use the built-in screws
M2.5 x 14mm double pass copper post
2
M2.5 * 14+4 copper pillars can be used instead. Considering that there are fewer copper pillars, double-pass copper pillars are recommended
M2.5 x 20mm double pass copper post
2
The UPS is fixed at the bottom, which can be replaced by M2.5*20+6. Double-tube copper columns are recommended for easy installation
M3 x 10mm hexagon socket screw
4
Used to fix the cooling fan on the top
Among them, it is recommended to use acrylic for the side and bottom plates, which will look good. I also provided the dwg file for acrylic cutting. Then the side panel will be very monotonous because of the blank, you can engrave some patterns on it, just like me.

I will post a video later
