EDIT: I need to read more fully into these things...
First, did you put the grey-black plastic spacer behind the thrust bearing (the thing with little rollers)? If so, remove that. That might get you close to the 10mm mark without the extra lasercut spacers behind the flange.
Second, make doubly sure that the collar (the one that's tightened around the auger shaft with a hex key) is butted up as far to the front of the auger as possible when it's loose. Tighten it there. This will also help alleviate that problem. If this and the spacer removal are done and the shaft still sticks out too much (when you're pushing on it to compress the thrust bearing), then put the lasercut spacers back in right behind the flange and between the front face-plate.
Third, the hex-shaft on the auger can be pretty darn loose on the hex-coupler that connects it to the motor. Make sure it can slide easily.
Well, thats a small issue with the auger sticking out too far, I can fiddle around with spacers/washers etc and eventually get it to 10mm fine - its the acrylic that doesn't fit properly after that.
My acrylic wants to twist a little and won't let me put the 4 x m5 long black screws through the side panels, the aluminium block is always in the way of one side and blocks the bolts exit.
I might actually redesign a new housing for this thing, I really don't like the way it's coming together and I don't see why I couldn't print one that is both large enough to fit the PID comfortably without squishing everything and also will allow me to get all the spacing correct without having to do all this stuffing around. I am not sure why at 2.1version of the kit it is still so rough in it's build state? I was sort of hoping that by waiting this long most of the problems were ironed out but I seem to be getting kicked in the butt.
If you scroll up you will see my hex adapter was way too tight and had to be filed down, but even still its not as loose as I would like so I am going to have to re-do that again as it's getting stuck/jammed on the auger and wont budge on the odd occasion.
I had my case be a little finicky too. Just loosen the four flange bolts to the point that the face-plate can be moved with force but stays still on its own, then put the sides on and slide the bolts through. Line everything up and then pull the side plates back off and carefully tighten the four flange bolts again. Now the face-plate should be in a position that it will fit together without binding too much. You may have to try this a few times. I had to assemble and disassemble mine about 6 times.
