Need NM-200 Measurements

[MRM RCModels]

All,

I'm designing a few peripherals to kill time before my NM-200 is delivered. Can someone post dimensions for the mill end mill mount (L1 & D2) and retainer ring (L2 & D1) in the attached pic? I'll start a build thread once the first project is started.

Thanks
