This is a simple 1u mounting solution for the Raspberry Pi 4. This model includes the option to accommodate a 40mm fan (or any other component with holes spaced 32.5mm apart).

Mounting Hardware Required:

• 2x M4x20mm bolts with hexagonal heads
• 2x M4 nuts (for securing the Raspberry Pi)
• Optional:
  • For fan installation:
    • 2 or 4 M3x25mm bolts
    • 2 or 4 M3 nuts
    • (Note: the fan holes in the project are 5mm in diameter, so you can also use M4 or M5 bolts if the fan permits it)

Should there be significant interest in this project, I may consider redesigning the fan mounting mechanism and developing a holder without a fan.
