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 = whole
180 = half
120 = third
90 = fourth
72 = fifth
60 = sixth
You'll need OpenSCAD 2019.05 or later for this to work.
Print Settings
Printer Brand:
Anet
Printer:
A8
Rafts:
Yes
Supports:
No
Resolution:
0.2 mm
Infill:
10%
Filament: AmazonBasics PETG red
Notes:
3 top and bottom layers, 2 perimeters. Use a raft for adhesion. Clean up stringing with some sandpaper if needed.
As designed, the spacer will print upside-down. In use, the tapered edge faces up and the edge with the lip engages with the outer edge of a dehydrator tray.So far, I've not glued mine together. It's a good-enough fit for the tray diameter that I think I'll keep it in pieces so it doesn't take as much storage space. With dehydrator trays on top and bottom, it'll stay together well enough to dry a roll, so long as you don't bump into it.
I also bumped up $fn in the SCAD file from 128 to 1440 to produce a more round shape. Printing from SD card (instead of streaming from OctoPrint or something similar) might also be a good idea.
