This is a Pod for a 60mm Turbo boost gauge I 3D printed.
I wanted a way of mounting a gauge without the need for drilling and cutting into the cars interior or deleting the clock. The holder uses friction to grip the top of the steering cowl. A ball and socket attachment allows for some adjustment to suit the driver.
The mount can be slid into place without removing the steering cowl by lifting the rubber flap and sliding to the left. Then push the ball into the socket joint through the nut, adjust for position and tighten down.
I've posted the design and the files online if you have access to a printer and would like one yourself. Turbo Gauge Pod
I'm sure someone with better 3D modelling skills than mine could greatly improve it. When it's printed it needs to be sanded, filled and painted to give it a more OE look but if that doesn't bother you its good to use straight away.
I have found it works great and is very steady with no wobble or vibration noticeable.
