Case for little backup box

This project provides a housing for little backup box based on a Raspberry Pi 4.
It is based on a 3D drawing on the freeCAD platform. This drawing can be easily adjusted using an integrated table of dimensions.

For more information visit outdoorbits/little-backup-box. In lbb's Wiki you will find all information needed to plug it all together.

Little Backup Box in this case, including a ssd1331 color display, buttons for menu-navigation and a pwm-controlled fan

The standard drawing assumes the following components:

Raspberry Pi 4 Model B
Display ssd1331 (RGB color display with 96x64 pixels)
Fan having external dimensions 30x30mm, hole spacing 24mm; prefer PMW-versions
Micro key buttons 6x6 mm2, mounted on a board
15 pieces of jumper wire, female
4 screws M2.5 x 20 mm for the case
8 screws M2.0 x 8 mm and nuts for the buttons
Hot glue to stick the display

Customize drawing

If you use different hardware components, you can adapt the drawing. It's (relatively) easy to adjust dimensions:

Open the FCStd file with freeCAD
Open the "dim" spreadsheet in the tree view
Change the appropriate dimensions
Mark the respective body in the tree view (e.g. "Bottom")
Export the stl file (File - export...)

The whole case

The bottom

Inside view of the top

Fan, look for "5V Fan - Software-Controlled"

Mico buttons, look for "Micro key button"
