Summary

its thick enough to be stable. thin enough to work and closer than the stock mount.
this mount is within 1mm of the bed when the bltouch plunger is depressed. it is not 5mm away. making your "baby z stepping" more manageable and easier to eye up. it is roughly 0.6mm from the surface. the plunger on the bltouch depressed something like 0.5 before it is registered, thus, this is about as close as you can get it. i hope this made your Bl touch easier to mount and work. you will still have to change the eeprom>motion>babystep z> 0.000 to -0.59 (negative) (then save settings) or something still, depending on bed surface, i imagine.
