As an alternative to a lazy susan corner, here is an arrangement that will work for you frameless folks.
As seen, the corner box is 16-1/2\" width, and solid wood bevelsawn fillers do the gaps. The reveals are shown to bring the between-fronts reveal in at 1/8\", when working with nominal 3/4\" fronts.
This 16-1/2\" corner-plus-fillers is a plug-in for a 36x36 susan corner.
Doing a corner such as this instead of a susan gives a nice boost-out to the countertop, enabling space for a nice fullsized built-in microwave atop the counter.

We've used that system before Gene with a 1\" filler. We have found through trial and error that if you don't leave a wider gap, the door will touch the knob of the other door.
