The “real” Volkswagen counterparts to these models have a propensity to spontaneously vanish from the vehicle, due to aging plastics and a harsh, vibration- and wind-heavy environment. I have literally never seen an actively-driven 1988-1993 Cabriolet that actually has these pieces in place, but the parts are real and do exist!
This model was recreated by hand from measurements taken from the one real VW equivalent I have ever come across. It has has tighter rear “clips” than the original, so it shouldn't fall out quite as easily. But if it does… you can always print more!
Filament shown in the picture is Canadian Filaments Black PLA, which actually comes out a little bit satin extra-dark grey - a lovely match for the grille that this snaps into.
The author marked this model as their own original creation.
