Rivet Nut Spacer (Parametric)

I created this rivet nut spacer during my campervan conversion (e.g. Fridge Cabinet Build/Install). The spacer is used whenever there is a gap between the wall and the cabinet to be installed. This prevents the rivet nut from being pulled out when fastening the screw, and prevents deforming the wall and/or the cabinet. 

This is a parametric model, to allow changing the total length of the spacer (wall-to-cabinet distance).
Use “Customize” button at the top of this page.

I tested the spacers with the following rivet nuts:

• M6 Rivet Nut.
• M8 Rivet Nut.

Tips: 

• I like to preinstall the spacer over the rivet nut with a dab of CA glue. This way, the spacers stay in place when the cabinet is removed/reinstalled.
• Use a high-temperature resistant filament (I'm using ABS).

Photos coming soon.
