These snap ring pliers are what you will need to assemble/disassemble your B0 (B Zero) if you opt to do it yourself.  They can also be used for for the Venus and Mercury diffusers as they are adjustable.  We figured we would pick up a few sets and make them accessible to our customers who may need them.  We aren't planning on adding a bunch of tools to the shop!  LOL  These have interchangeable heads for various setups.  There are some logs on the market that use snap rings for their stems so these will help there too!
