Gridfinity USB-Female Holder

I made a USB-Female Holder for little adapters or usb sided things (for Gridfinity 2x2), I didnt really found something that suitet me so I made my own. It can hold up to 12 USB-Adapters + 1 capture card (the USB thing has to be on the right spot) and it has a thing that can hold bolts, a big screw or something with an diameter up to 6mm, in my case a adapter for my guitar.
