Introduction
I really enjoyed the original case that this is based on (https://www.printables.com/model/65824-raspberry-pi-3-case-with-homematic-rpi-rf-mod), but my MK3S+ had difficulty creating a truly flat lid. The one screw attaching the lid to the base would cause one side of the lid to not lay flush.
Using the original for measurements, I remodeled the case to be a little larger and accommodate M2.5 bolts and nuts for secure attachment. I also didn't need live access to any Raspberry Pi ports except the USB/Ethernet/Power, so I closed off all other ports. For debugging, you can remove the lid and access all the ports without removing the devices from the base.
Requirements
For this build, you will need
- hardware
- (4) M2.5x10 (M2.5x8 will also work)
- (5) M2.5x12
- (9) M2.5 hex nuts
- tools
- M2.5 drill bit
- hex key
- (optional) super glue
Printing Notes
When printing the lid, paint on supports to the counterbores of the five bolt holes.
Post Processing
Mounting Holes
There is a 1-layer tall bridge under all the mounting holes in the base. Use an M2.5 drill to remove this layer
Captive Nuts
Insert all (9) M2.5 hex nuts into the base. Use your Allen key to align the threads of the nut with the hole.
Optionally, secure the nuts with a dab of super glue (along the rectangular hole where the nut is inserted, not from above or on the threads!).
Heat set inserts would obviously be easier to design for and wouldn't require any of this processing, but I chose to use hex nuts for lower cost and not needing a soldering iron to install.
Assembly
- separate the RPI-RF-MOD and RPI boards
- install the RPI-RF-MOD board first with (2) M2.5x10 bolts
- (optional) install the external antenna (see below)
- plug in the RPI into the RPI-RF-MOD
- secure the RPI with the last (2) M2.5x10 bolts
- secure the lid to the base with (5) M2.5x12 bolts
External Antenna
I left space for an external antenna mount (6.25mm SMA adapter). I will be testing performance with an Eightwood 868Mhz antenna: https://antennasky.com/collections/868mhz-antenna/products/eightwood-868mhz-antenna-sma-antenna-sma-male-adapter-sma-female-pigtail-cable-rg178-15cm-6inch-for-cb-radio-cb-antenna-gsm-wireless-wifi-router-nfc-rfid-cb-radio-walkie-talkie-ham-radio
