Porsche 944 dash vent inserts

The dashboard on the porshc 944 cracks and when recovered it is hard to get glue into the vent holes and hold the vinyl down. You can buy these inserts or you can print them yourself. It eliminates the problem of glue:ing in tight spaces and risking to have contact cement on your new vinyl dashboard that you just spent 30 hours sanding, cleaning and recovering, don´t want to trip on the finish line.
