USB thumbdrive holder for M8 rod

Edit: V2 added, which uses less material
Updated V2: The script was wrong, H and B were swapped! Oh my.

Remix of the classic endstop holder to hold a USB thumbdrive. Useful if you store firmware, calibration data and replacement parts on a USB stick and keep forgetting where it is. It can also be used to hold the plug of the printer's cable when you're not using it.

The design is parametric, so you can change the size of the hole if you need to; for example to hold tools.
