Deep Rock Galactic Flare with inserts for ESP32 18650 BluetoothWifi

A model of the flare from Deep Rock Galactic. The model has several components that can be printed in different colours.

Additional Required Parts:

• ESP32 DevBoard “TTGO T-Energy T-18” or similar
• “18650 Battery" for the DevBoard
• “WS2812 LED Strip”. With max 8mm width (which means, get strips with 30 or 60 LEDs per meter, do not get 100 LEDs/m)
• Firmware for the DevBoard: https://install.wled.me/

if you search and shop for the terms in quotes, you should find them easily

Materials:

• For transparent parts, I used transparent PETG from Extrudr and tecbears
• For gray parts, I used a dark gray called „metallic“ PLA and XPETG from Extrudr. Anthrazit or Eisengrau are probably close to that.

everything was printed with 0.6mm nozzle and high layer height for more stability.

Assembly Tips:

• Check length of WS2812 strip that is needed and fits onto the ledguide, then cut ledstrip to size. Plan ahead on how you want to connect it to your DevBoard. e.g. leave the wires on.
• Check that guide in cap and ledguide are rotated correctly so battery has space
• Check space left by ledguide before fixing ledguide mount to led guide
• Hot Glue led strip to led guide
• Hot Glue esp32+18650 board to ledguide
• Hot Glue ledguide mount slide onto ledguide. Careful to use right side so battery has enough space at the bottom
• Optional: I recommend adding a MosFET between WS2812 GND and battery GND with a 8k pulldown of Gate to GND to save battery. The Gate can be connected to a pin configured as relay-pin.
• Everything clips together, except the bottom part where the charging port is. This just holds by friction, so you can reach the switch, button and charging port.

Button & On/Off Switch:

• All but one gray-to-transparent parts have latches to clip together
• The one without latches, is made so you can slide if off in order to reach the buttons.
• The button on the dev-board can be configured to change your presets
• The web-interface software Power-Button will only power off the LEDs but the μC will still draw power from the battery. Use the physical power-switch on the dev-board if you store your flare for longer than half a day or your 18650 might get deep discharged.
