VW Transporter T5 rear panel filer
When using the standard vw rear panels they have a gap at the bottom, i have created this to fill that gap whilst keeping a path for the vent to equlaise pressure to the outside when closing the doors.
This has some support built in, shown in blue in image, this can easyly be snipped out.
I have included a step file so you can fill the holes or add a bigger hole for cables etc
