Raspberry Pi 4 case with fan customizable / parametric (also fits 3 2 B+)

thingiverse

See v2 here which fits any fan size up to seventy millimeters. Can be customized for larger than seventy millimeters: https://www.thingiverse.com/thing:3717622 Remixed from nigeljohnson73's design here: https://www.thingiverse.com/thing:629886 Added a customizable / parametric fan mount. Supports many case fan sizes, perhaps up to sixty millimeters in diameter. Fan sizes up to fifty millimeters are included. Screw separation can be looked up in the table below. E.g., a forty millimeter fan has a screw spacing of thirty-one point eight millimeters, which the model can be customized to fit. Secure with M3 / M4 bolts (or another size, if you customize the screw hole diameter). Customizer doesn't work with imported models, so use the OpenSCAD client to customize. Needs pi_front.stl in the same folder as pi_front_with_fan.scad RenderModels.sh is a bash script which renders models for thirty, thirty-five, forty and fifty millimeter fans. Lookup table for fan sizes: Fan Size | Screw Spacing --- | --- Fifty millimeters | Forty point eight millimeters Forty millimeters | Thirty-one point eight millimeters Thirty-five millimeters | Twenty-eight point eight millimeters Thirty millimeters | Twenty-four millimeters
