Beer crate stand

… and found the answer, when I was going for a new drink:

The bee crate stand!

• Versions for three, six or nine crates per stand. 
• Just print a left and a right side frame and six bars of your desired lenght.
  (Atttention! The frames are not symmetric, you'll need to mirror.) 

You'll need 12 pcs M3 hex socket screws, DIN 912 type or similar. 

Any screws longer than 10mm should work, but if you plan on loading heavy battery boxes on the 3x3 stand, I'd recommend using screws as long as possible to prevent the bars from bending. (A bench vise and a electric drill are very useful for this, but be careful! Long screws get very hot, so give it a cooling break inbetween and go on to the next screw, there are plenty;)

very usefull addon!
