Enclosure for BSFrance / DIYmall LoRaM3-D boards, customizable for others

I got one of these STM32 LoRa boards https://bsfrance.fr/lora-long-range/1367-LoRaM3-D-F303-LoRa-STM32-OLED-LiPo-development-board-long-range-ARM-SX1276.html on eBay and figured if I'm going to develop for it, it needs a case so I can carry it around without having the antenna cable dangling, risking damage etc. But this is one of my most customizable box designs yet, so you could probably customize it for any board that has a display, some number of buttons, and cutouts at arbitrary places, and a USB jack along the left edge. I got some inspiration from https://www.thingiverse.com/thing:2670713 but it ended up being more satisfying to start over than to modify it. I attached the board to the bottom part instead of the lid so that the antenna and the board would be together; but the downside of that is if you want to put something underneath (like a battery), those corner supports might be in the way. The box can be made deeper to accommodate a battery though. I will probably try later. After the print was done, I used a 3D printing pen to "weld" down two corners of the PCB. I think I like this technique: easier than finding the right-sized tiny screws and printing the right-sized holes for them. I'll see how easy it is to remove if I ever need to though. I don't plan to add any more electronics right away, just see if I can write an app that displays some data that it receives from TTN. So the box is currently only big enough to hold that board, nothing else; but the margins on all 4 sides are customizable.
