AirWick Base or Spacer for Refills

I recently purchased Airwick Freshmatic automatic freshener. When it ran out, I picked up some re-fills which were more affordable than the same brand. Unfortunately, the replacements were short in height and wouldn't work. 

I took it to TinkerCAD to design a simple model that acts as a base or spacer for the replacement re-fills. The replacement re-fills now just sits on this spacer and works perfectly. 

I hope this model is useful to others.
