This is my first attempt at a simple tubular snorkel that I designed for my FTX Outback 2 Treka. Doesn't take long to print so feel free to try it on other models. I have created a screw hole at one end and a pillar mount at on the side for securing to the car. The snorkel top just requires gluing in place. Some sanding and trimming may be required to get it how you want it. I have put the pillar mount on a slight angle and strengthened it as the first version snapped off pretty quickly when the car rolled over.
I printed this with the pillar mount up off the raft with support so the finish looked better on the side you can see.
