I did this [An XLR cable adapter - QA40x - QuantAsylum Forum](https://forum.quantasylum.com/t/an-xlr-cable-adapter/1689)

and I’ve been very happy with it, although after 3d printing it I redid it in aluminum because there’s a fair amount of torque with these connectors. The connections are extremely short and noise pickup is minimal. It does, however, exclude using the BNCs standalone.
