Some helpful printable widgets for LoRaWAN and IoT projects.
The Things Outdoor Gateway (TTOG) has a SIM card slot protected by a waterproof cap. This unscrews from the unit, but it's a large nut size so you need a good spanner set to find the right size, or a really big adjustable spanner. We've designed a printable spanner that makes it easy to open and close.
No printer? The spanner is available to buy here!
The spanner is designed for easy printing with no supports. We print on our Prusa i3 Mk3 using the default 0.2mm SPEED settings and at 20% infill.
