Gridfinity Lab Squeeze Bottle Holder

This is a 2x2 Gridfinity organizer for a 500mL straw squeeze bottle.  You often see these in lab or work spaces.  Mine is about 72mm in diameter.  I mostly use it to wet a soldering sponge or clean up little messes that do not require solvents.  

I used Gridfinity Rebuilt just to generate the base plate and cube.  I have yet to fully dig into this openscad project enough to fully understand it.  It was useful to get started.
