T-Beam Meshtastic iDroid Case

Model is available on Onshape for remixes/modding

Blah, blah, blah part:

Made this while playing through and finishing Metal Gear Solid V around 2022 which gave me the idea to model and design a case for my pair of T-Beams. Based off the photos of the official iDroid case for the iPhone 5.

Parts List

What to Print:

• “Required - Front Panel.stl”
• "Required x2 - Button.stl" (Print 2 for standard setup or 3 if you want east access to the reset button)
• “Required - Reset Button.stl” (Not needed if you're printing three buttons)
• “Required - Electronics Housing.stl”
• Your battery choice (Choose one):
  • (Files with “Battery EZ…” features easier to print model with an unfurnished back similar to my prototype)
    • 18650
      • "Battery - 18650.stl" or “Battery EZ - 18650.stl”
      • “Battery Lid - 18650.stl”
    • PS4 - PS3 Batteries
      • “Battery - PS4-PS3.stl” or “Battery EZ - PS4-PS3.stl”
      • “Battery Lid - PS4-PS3.stl”
    • 103450
      • “Battery - 103450.stl” or “Battery EZ - 103450.stl”
      • “Battery Lid - 103450.stl”
    • Oddly shaped battery measuring 101x27mm (That I salvaged)
      • “Battery - 101x27.stl”
    • Blank
      • “Battery - Blank.stl”

Printing Notes:

• Almost all the parts needs support except “Battery - Blank.stl” or their “EZ” counterpart.
• I printed and tested most of the models in PLA so I don't guarantee it'll print and fit in other materials.
• For post-printing, don't forget to paint the slider and accents to your preferred color. The lettering is hard to paint especially spray painting.

Materials Needed:

• LILYGO TTGO T-Beam (Tested with V1.1 but newer versions such as the M8N or SX1262 may work as dimensions looks similar but I don't guarantee it so check the Onshape model to verify)
• 0.96" (inch) OLED I2C Display
• Your choice of Antenna
• Extension Cables:
  • 6" (Inch) SMA Right Angle Female to SMA Male Extension Cable (The female end should be right angled)
  • 20cm 4pin JST-XH Male to Male Extension Cable
    • To make one:
    • x4 20cm 22AWG/Gauge Wires
    • x2 JST-XH Male Connectors
• If you're not installing an 18650 battery
  • x2 10cm 22AWG/Gauge Wires
  • x1 JST-XH Female Headers

Screws:

• For the “Required - Front Panel.stl” & “Required - Electronics Housing.stl”:
  • x4 M2x5mm Counterbore (Secures the front panel to the housing)
  • x4 M2x8mm Countersink (Secures the OLED display to the front panel)
  • x4 M2 Nylon Nut (To tighten the OLED to the front panel from the PCB side)
  • x3 M2x4mm Countersink (Secures the T-Beam to the housing) 
• Your battery choice (Choose one):
  • All batteries (18650, PS4, PS3, 103450, etc.)
    • X4 M2x12mm Counterbore
  • “Battery - Blank.stl”
    • x4 M2x5mm or M2x6mm Counterbore

Behind the Scene Stuff:

I started this around mid April basing off on Sentinel Co. Ltd.'s iDroid case for the iPhone 5 but with some modularity in mind. Finished my first functional prototype with the back being unfurnished on early May of 2022. I had planned to post that models but seeing the rat nest of features and the need to write an full instruction document put me off for a while.

Until February 2023, I had made it an New Years resolution to post more of my creation on site like this so I began cleaning my mess, improving it, adding details to the unfurnished back and added support for other batteries I have lying around or salvageable in my house. The instruction document/pdf will take some time to type out so for now I will list out the required materials.
