basically the title. there isnt a ton of info about the 3-in-1 tool head on the express. while my access to 3d printers, CNC, and waterjet machinery should let me make many of the parts myself, I cant find references to the weird Drill and nozzle combo tool showcased on the express 3-in-1 nozzle, neither inline or in the store. I definitely dont have confidence I can make one myself, so does anyone know where to buy this piece? they arent selling the 3-in-1 head or any of its components on the farmbot store to the best I have found.
