Enclosure for DIY LoraWan gateway for "The Things Network"
This is a simple and compact enclosure for a DIY The Things Network  gateway.
For the gateway itself you need tho follow the excellent 'From zero to LoRaWAN in a weekend'  and use the coredump.ch backplane .
The enclosure is easy to print, no supports needed. Note that dimensions are optimized for a 0.35mm nozzle and 2mm layer height.
All parts are designed with a 0.5mm tolerance for a tight fit.
The M2.5 and M3 nut slots in the base plate provide a very tight fit so that the nuts won't come out once pushed in.
My enclosure is printed with Nanovia PETG-CF, but any filament should do.
The case can rest on its 4 feet, or can be wall mounted with the adapter instead of the feet.
Securing the Raspberry Pi
The Raspberry Pi is fastened to the bottom plate with M2.5 screws. The coredump.ch backplane is delivered with 2 nylons standoffs. The easiest is to push the nylon screws from the bottom of the case ans secure the RPi by screwing the standoffs on top.
For the 2 others points, push the nuts in the case and screw from top.
- The DC power is connected to the backplane either to the 5V input or the 6.7-28V input, depending on your power supply.
- The fan is connected to the Fan output of the backplane. I used a screw terminal instead of the header. You can then control the fan from the Raspberry Pi.
Aside the gateway as described in , you will need:
- 1 Panel mount DC power connector
- 1 5V 25x25mm fan
- 2 M2.5x8 screws & nuts for the Raspberry Pi (The Coredump backplane comes with 2 standoffs and screws/nuts)
- 3 M2.5x16 screws & nuts for the fan
- 4 M3x8 screws & nuts for the feet / wall mount
- 4 M3x8 screws with flat head for the sides (No nuts here, they are screwed in the enclosure tabs. So not over tight!
