My Cosori filament dryer did not come with enough spacers to comfortably fit more than one roll of filament at a time, so I made this to correct that. I printed three copies at once standing up in white Overture Easy PLA without supports. A brim might help, and a higher temp filament might be required if you want to dry higher temp filaments. I joined mine with super glue on top of one of the rings the dryer came with using clamps on the tabs at the side and then filled in the gaps with jb weld.
You could extend it if you wanted. As the young kids say: Z's bees bussin at the limit fr fr no cap. This is as tall as my printer supported. I measured and it still gets to the correct temp at the top.
