Dehydrator expansion rings
Dehydrator expansion rings allow you to dehydrate something taller than one inch.
The rings are divided into 8 segments.
I used the default Afinia settings. (Your mileage may vary.)
Quality: Normal (speed)
0.30mm Z-resolution
I did not use a raft. A flat and level (perf-board) platform shouldn't need one.
The 2" tall sections each weigh 25g, plus 2g support material.
Search out and remove any hidden little bits of support on the edges so the pieces fit perfectly to eachother and to the trays.
I recommend you first print one or two sections and if that is a success, then go for four (or perhaps five).
The sections do not exactly snap-fit together, but they do align themselves.
I don't know the best way to assemble them to get a perfect ring, but aligning them atop one dehydrator tray, with another tray on top them to line everything up correctly, and then gluing them together piece by piece is one way.
Do it on some newspaper on a flat surface.
However you do it, be careful to maintain a flat, circular ring of the correct circumference.
Use ABS adhesive to join them.
[Update: Rings are fragile so I highly recommend welding these together. Far superior to gluing them. http://www.thingiverse.com/thing:1807093 ]
I tested the ring with this dehydrator at its highest temperature, 160F, for a couple hours and nothing out of the ordinary happened. I think these will work out OK.
I design in inches. The STL files are SAE. If your software imports impossibly tiny files, scale up (X, Y & Z) by a factor of 25.4. (There are 25.4mm to the inch).
