T3S3 E-Paper Enclosure for Blackout Comms (or whatever)

This is an enclosure for the Lilygo T3S3 E-Paper. I designed it to enclose the T3S3 for the home base station and mobile (truck/solar) base station of my personal Blackout Comms off-grid mesh comms cluster. However, it can probably work for whatever else you'd want to build on this dev board.

Note: Blackout Comms was previously named “ChatterBox”, so you may find references to that in the instructions. The instructions are still valid for either firmware.

You will need M2 knurled nuts to melt into the case back and M2 screws (see the assembly instructions PDF for links). Other than that, this case is pretty straightforward.

I designed it so if you print as oriented in the all-in-one 3mf file, you will have very little waste and almost no filament to cleanup after the print.

• Designed for a Blackout Comms node, but usable for many other things
• SMA connector, USB port, and SD card slot are all accessible
• Stable enough to leave free-standing
• Built-in brackets allow mounting with velcro straps/etc
• Enough space for a 2000 mAh LiPo battery (LP103454).
• Area in the upper corner for a DS3231 realtime clock or GPS antenna

chatter_mini_node_paper.3mf - If you use 3mf, all you need is this one file

If you will print the STL files, you'll need to print all 3 of them. I use ABS for the enclosure front/back and PLA for the power switch.

I also included instructions for building and flashing a mesh node, as well as a user guide, but if you're not building a Blackout Comms node, you won't need those.
