I designed a, in my opinion, pretty elegant holder for FlowTech nozzles and accesories like new silicone socks, as well as a small wrench to change the nozzle. The wrench is some random Chinesium wrench I got with a MK6 nozzle kit from Amazon a long time ago, so your milage may vary with fitment of your Wrench of choice. This is why I also added a .step file, without rounded edges, for easier modification if you are not using fusion.
