Fed up with breaking your heat break when changing your nozzle on the Hemera? Then this tool is for you. Note, it's very specific to my setup, so unless you are using my Hemera mount, Volcano and fan duct, you will probably need to modify it.
It also requires three lengths of 6mm steel square section rod cut to size (6mm door handle spindle will do just fine and is available for very low cost). A hacksaw should do it. It also requires a long 7mm steel hex wrench socket.
