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

See v2 here which fits any fan size up to 70mm. Can be customized for larger than 70mm: 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 60mm in diameter. Fan sizes up to 50mm are included. Screw separation can be looked up in the table below. E.g. a 40mm fan has a screw spacing of 31.8mm, 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 30, 35, 40 and 50mm fans.
