I've started work on the case again and will print another in CF and add some aluminium panels.

I am making plates for connectors that bolt to the chassis. so far only 2 plates , 1 for the mini XLR inputs / outputs and 1 panel for the AES IO mini XLR and 1/4" headphone sockets.

I have no idea if this 3d grab cad page will embed but its a rough idea!
