Extension ring for Menuett mushroom dryer

thingiverse

This is an extension ring for the Menuett mushroom and fruit dryer sold at Jula in Sweden, which I use to dry my filaments. Putting filament rolls in this dryer normally forces you to cut the centers out of a few of the included trays, but with this extension ring you don't have to do that. You could also print a couple of them and dry two rolls at the same time. The ring is a total of 82 mm high, which with one of the original trays in the bottom and the lid allows for drying of rolls around 100 mm thick. I originally printed this in PLA. That warped quite heavily after a few uses, so I can't recommend using PLA unless you will use only the lowest temperature setting. I've since reprinted it in T-Glass (PETT) which I had a few old rolls of, but using PETG, ABS, PC or something else which is more temperature resistant would work fine. You will need supports under the overhanging lip.
