Helium Mapper Case for Heltec CubeCell (HTCC-AB02S)

UPDATE 2/10/22 - Added a new lid version with much better buttons and a few tweaks to facilitate printing. Doing a filament swap does a nice job of highlighting the logo and button icons.

Quick remix of philltran's mapper enclosure to address some issues using a higher gain GPS antenna (tested with https://www.amazon.com/gp/product/B078Y2WNY6), add an external SMA connector (https://www.amazon.com/gp/product/B07NVT8FMT or similar), and permit a larger selection of batteries. Took the opportunity to tweak a couple surfaces and throw a little branding on it but would still like to improve the buttons and make them a bit more tactile and add retention clips for the board...perhaps in the next version. Note that different GPS antennas may require changes to the slots/guides for clearance and thicker antennas may need to go on the side as in the original design, I located it on the top for optimal reception when on the dash of my vehicle.

Depending on printer setup and tuning very minimal cleanup should be needed. With PETG you may get some stringing on the underside of the buttons or inside the case, most notably in the GPS antenna rails. Both are easily touched up with a razor knife.

Modded to allow using a higher gain GPS antenna, add an external SMA connector, and permit a larger selection of batteries.
