Travel trailer drain tray

The drain tray that my travel trailer came with had an indent that was a good inch larger than the drain assembly.  That meant that the water would pool in this gap and stay there until it evaporated or I got annoyed enough with it to go get a paper towel to soak it up.  To fix this I designed a replacement that removed the gap.  Now the drain assembly fits perfectly with minimal gap.  Don't forget to reseal everything when you install.  I would recommend PETG or a similar heat tolerant filament to avoid warping in the heat.
