Xol Hotend Mount Mk8 and 3010 fan

Want to play with a shiny new Xol toolhead setup, but don't have a shiny new hotend to go with it? Try this mount for Xol that accepts a Mk8 hotend. The V1 printed nicely, but I had trouble getting access to screw the hotend down; I've added a V2 where the heatset inserts mount on the opposite face, and the screws are installed from the rear - much easier! Build up according to the Xol guide, noting that the Mk8 hotend needs an additional pair of heatset inserts installed on the rear face.
