No Drop Nuts for Micron+ Formbot and LDO

I modified the original No Drop Nuts mod to make assembly of the Micron+ 180 a lot easier. The 10 mm retainer only has one guide that can be easily removed. The retainers hold the nuts in place even without the guides.

Two of these can be put together and it will be the exact distance apart for the bearing and belt screws on the gantry corners. There is also an offset in the nut position so if they are placed in different orientations it provides 3 different spacing options.
