Viper 509u Ultrasonic Bracket for Holden VE/VF or Pontiac G8

Upon installing the Viper 509u I wasn't too fond of the look and if they were knocked they would have to be readjusted.

Along with keeping up the appearance of my vehicle I was wanting something a bit neater then the provided bracket, so I came up with the idea to design a new bracket which made it look factory fit. So as seen, the design I've come up with is to replace the air bag clip on the A pillar.

These brackets have been designed to angle each in the back seats, so with that being said I'm not sure where they would point in a ute.

More design information below

Post-Printing

After printing the parts, I took one of the airbag screw covers into Bunnings and got them to paint match it which I got a sample pot. I then gave the parts a bit of a sand then painted them on which turned out pretty decent, the only down-side to brushing the paint on was brush marks. So the only thing I would change it to get the same colour in a spray paint can.

Here is the sticker they put on it, I'm not sure if these numbers will get you the same colour but they might be able to match your airbag screw cover too.

How I Designed This

As you can see in the pictures below, I wasn't too fond of these standing out. Not that they looked bad but just stood out and I like everything looking more or less factory finished, hiding things when possible and things that do stand out, making them blend in with the surroundings.

To get the airbag clip shape I removed the A pillar then holding it on an angle as if it was in the car (why didn't I just take the photo while it was in the car? good question...) so I then ported the photo into DesignSpark and started tracing the shape, and after a bit of trial and error I managed to get the shape perfect.

When designing this bracket (as mentioned above) I wanted to design something to make them fit into the factory look of the car. So when finding where I wanted them located, I printed a flat panel to clip into where the airbag A pillar cover is, having a panel perpendicular to the airbag cover testing out where to aim the sensor resting a laser against the panel to get the desired angle, once figuring out the angle I proceeded to construct the final product

Then it occurred to me, how would I get something like this inside the new sensor housing? The only way I could see it working was to withdraw the cable, then tread it through the sensor housing then feed the cable back to the alarm.

Along with resin (SLA) printing comes the down-side to a part this size. I found the tabs were delicate, so imagine breaking the housing then having to print a new one, unplug the sensor pull out the wiring, feed it through the new housing then feed the wiring back to the alarm.

So there was no way I was doing that more then the one time needed to use these sensors (seen further below) so I redesigned the housing.

With this new design, it allows the sensor to be slid in from the back.

Note: I will include an untested prototype where(as seen below) it has a separate base plate to the rest of the housing. The idea behind this design was so the top can be printed in resin for higher detail and the base can be printed in PLA so the tabs are stronger. However like mentioned, I never tested it. I planned on using this concept if I had to ever replace one of them. Bare in mind you can test them for yourself but the STL provided is for the passenger side only, so in order to get the driver side you will need to mirror the model.
