Audi TT Sill Drain Insert

I decided to have a go at printing this item as most on my 2004 TT were either missing or broken. It is not quite exactly the same as OEM but it fits well and appears to do the job.

Ideally, it should be printed in ABS but, due to it's fitment location, in PLA mine seem to be fine.

I'm new to 3D design and 3D printing so I'm sure some of you would find improvements to my design and feel free to tinker.
