A two part enclosure/case for a Raspberry Pi 4 incorporating a mounting for a cooling fan - with an additional separate fixing bracket for a custom PCB that controls the fan.
6mm M2 self-tapping screws are used to secure the Pi 4 into the case base and 8mm M3 pan head screws are used to connect the case lid to the case base. The screws/nuts supplied with the fan are used to secure it to the mounting on the case base.
Self adhesive feet are used to raise the case above the surface to allow cool air to flow in from beneath the case.
An optional addition is a set of clips that allow a small USB HD to be slotted in under the case as shown in some of the images.
More detail on the usage context is available from this link.
All the components use 1.75mm PLA and a layer height of 0.15mm with print details for each component produced on an i3 Mk3 shown in the table below.
