These are two VW Caddy Body Bungs Caps for the openings in the body that are a 45mm x 25mm oval shape. These two bungs fit snugly depending upon which one you print.
The metal one is for where the body has not been carpeted (straight into the metal body work). The carpet one is for where the bodywork has been carpeted with regular stretch carpet.
I designed these because although I have carpeted my Caddy I wanted to retain access to the space behind - I am running cables and electrics within this space, so want to have access for additions/changes.
The fit very snugly (especially the metal version), so be aware you may need to prise out. The carpet version is deeper so that it fits in further into the recess to account for the additional carpet depth.
Printed with PLA of an infill of 10% or 20% - makes no real difference.
