USB security box

Got tired of the wife and kids stealing my USB cables. I found another design on thingiverse but I wasn't happy with it, so I designed this one. No more cables have migrated to anyone else's devices. Confirmed snug fit with NOOT & RAVPOWER 60W 6 port chargers. Supports only needed for the mains power cord entrance. Has 3 CSK holes in the box for wall mount. #6 screw seems to be a good fit but I haven't actually mounted it. Lid is secured to box with #4 screws. I've included a picture of the screws I used for the lid.

For reference, the USB chargers I'm using are approx. (LxWxH) 4in X 2.72in X 1.18in or 101.6mm X 69.09mm X 29.97mm.

1/28/20 - Encountered a few thicker cables that required filing to fit previous 3.7mm slots. Updated model to increase cable slot width to 4.5mm.
