Description
This case is designed to fit the TTGO T-Display or similar HiLetgo microcontroller modules with 1.14 inch LCD screens.
The design is similar to my other TTGO T-Display cases but has room for male headers or wiring soldered to the board.
The body and cap files ending with "plus-4mm" are 4mm taller than the original, allowing for even more space for wiring or other purposes. The "plus-6mm" files allow even more space. The "plus-10mm-4mmL" are 10mm taller and 4mm longer in the interior (only 3mm longer exterior) to accommodate Lilygo or similarly-sized breadboard (adds a bit of length in the lower interior section).
The cap file ending with "bulge" provides more space within the enclosure on the end with the USB port (in case you are using a protoboard that extends a bit out that end).
For an enclosed version designed for female headers so the entire module can be plugged onto a male header base, see this thing:

The case is the same size as the largest original case (852540), but the battery divider has been removed, and the region around the reset button has been improved to allow tilting while inserting without jamming on the reset button.
Because the battery divider has been removed, more care should be taken to ensure that no metal contacts the circuitry on the bottom of the board.
With headers soldered to the board, there is still room for a small battery like the 401730 150mAh LiPo available on Amazon:

The case also has a more secure cap on the USB port end, with holes for locking pins (included in the print) or screws-- M2 x 4 as in this kit:

EDIT 2021/04/25: manually retriangulated cap. Original would slice OK and would pass STL checks, but the original had a poly that would render badly and could confuse some slicers.
