This model is an adjustable height funnel designed for Harvest Right Medium Freeze Dryer trays. It allows you to easily adjust the height above your desired container using 1/4" PEX pipes (or print the tubes.stl multiple times).

Inside the PEX, a 4 mm steel wire is used to align the base and funnel. The model is printed with 99 walls, resulting in solid parts approximately 3 mm thick. Feel free to experiment with infill settings.

Note that the object measures 220 mm square, so on my Ender 3 Pro, I had to scale it down to 99% in Cura for successful slicing.
