PB-Jar Vacuum Collection Cyclone

This tool is supposed to attach to a household vacuum cleaner to allow collection of material or small objects in a common size plastic jar. (Based off of one used for peanut butter.) The item as modeled should consist of three parts along with a stand-in for the peanut butter jar. As of this post it's a bit of a WIP, and it still needs threading to fit the jar. (Might be able to use foam tape or some such at the moment.) I'm fairly new to this, so it may need other adjustments.

No scale is set in the file, but the intended scale is 1 Blender Unit is equal to 1 Inch.

Added another file for the outer piece in .stl format. Added threads since I figured out how to make them reasonably. Otherwise it's pretty much the same. Hopefully the size is right to hold onto a jar, if not - give some feedback and I can try adjusting them.
