Sliced Filament Dryer Spacer

I have a dehydrator (a Nesco FD-61) that takes 13.5" trays...far too large for most 3D printers. Slic3r will cut models on the Z-axis, but after adjusting the original dryer spacer for my dehydrator, I didn't see a way to cut it into pieces.Fortunately, since it's in OpenSCAD, we can create a "cheese wheel" that will be subtracted from the spacer to cut it into a section small enough to print. On my Anet A8, I can cut a 90-degree section and print four of them (and all four will fit with not much room to spare).In addition to the existing variables, ANGLE can be set to something that'll fit on your printer:360 = whole180 = half120 = third90 = fourth72 = fifth60 = sixthYou'll need OpenSCAD 2019.05 or later for this to work.
