JAL- Raspberry Pi 3B case - 2020 mount, 30mm fan.

thingiverse

After downloading and printing numerous Raspberry Pi case models, I found none that fit well or had mounting options I liked, not to mention clearance for a cooling fan. As a result, I decided to design my own from scratch. Here are its primary design goals/features: • A clean fit for a Raspberry Pi 3B with sufficient clearance so it's not too tight. • Discrete mounting points spaced for attaching to a 2020 (or similar) rail and arranged to permit mounting in several different orientations and offsets, specifically on the side of my Creality Ender 3 Pro printer. • Ample interior air space and ventilation to accommodate heat-sinks. • An option to add a 30mm cooling fan if desired. • Raspberry Pi 3B status lights should be visible when in the case. • The Micro SD memory card should be accessible when in the case, also flush with the main body so it can be covered by tape or a label if desired. Note: This design should also fit a 3B+, as the mechanical drawings show the same dimensions as the 3B, but I don't have one to test and verify. This design currently lacks easy access to the I/O header on the Raspberry Pi. Vent holes could be cut-away if header access is desired. If I refine this design further, I may (or may not) add a header access door. The top of the case also needs improvement; there's room for improvement here, but every 'clip' or 'tab' I tried to add broke too easily, so that's on the backlog if I ever re-visit this design. Updates: • 25-March-2019 - Added Revision 2 of the lid, 5mm taller than the original, to allow more clearance for an internally-mounted fan.
