as the 510 is a little conical top plate is slightly more than 25mm, 26mm will fit without noticeable overhang, then come the conus which is approximately 2mm of hight and has a diameter of 30mm so for all bigger 26mm you will have a gap of about 2mm between the box and your atty, but even a 40mm like mason will fit with a rather small overhang on the box itself maximum without overhang would be approximately 36mm.
