Parametric bottle tray for small e-liquid/paint/nail varnish bottles

This "thing" is a rectangular (but not necessarily square) tray for holding small bottles such as e cig liquid, nail varnish, model makers paint etc. Basically it is a number of hollow cylinders but with solid bases, which are joined together by their wall thickness. It is fully parametric and should work with the thingiverse customiser. You can change the number of bottles wide, the number of bottles long, the overall height, and the base thickness. You can also change the inside diameter of the cylinders which should be the diameter of the bottles you want to use, plus 1 or 2 mm for clearance. You can also change the wall thickness if you want the cylinder to be thicker but I don't recommend that you go any less than 2mm.

There are no constraints in the code as to how many bottles, how big and how tall they are so make your design will fit on your print bed.

A small word of warning. Depending on how many bottles you use, the rendering time can be quite long and the resultant STL file can be quite big, although the print time isn't bad. As a guide, the default values I used in the Open Scad file produce a tray which is 5 bottles long by 5 bottles wide, with a diameter of 22mm (23mm cylinder i.d.) and 25mm tall. On my PC which is average to good speed wise, the rendering time was about 2.5 minutes and the resultant STL file about 4mb.
