Gridfinity : Parametric Bottle with Knurled/Fluted Cap

I've created a parametric bottle with a knurled or fluted cap that scales up as large as desired for the Gridfinity system. 

I've included STLs for some basic sizes, and my Fusion360 Archive file so you can generate your own. I like the fluted version better, because it is way easier to manipulate in Fusion360, which brings me to: 

WARNING: Your computer may scream at larger slotsWide numbers with the knurled cap f3d file, depending on how good it is at math. (My MacBook Pro took over 5 minutes to generate the 3x3x18 bottle.)

If you don't have Fusion360, and are looking for specific dimensions, let me know and I'll try and add it to the pre-generated STLs.
