Flux Dispenser remix of a remix

I made a few small changes to suit the M6 bolt and nuts I had:

• My bolt would slip in the barrel nut, so I enlarged it a little to fit an actual 10mm metal nut.
• Modified the handle to fit the new barrel nut and enlarged the holes for the m3 bolt
• Modified the dispenser m3 bolt hole as it was also too small.
• Adjusted the knob to fit a 10mm nut as opposed to 11mm.
