Dial Gauge - centrally mounted

Model 3: This is a version for a dial gauge where there is a mount on the back of a dial for support on an arm attached to a magnetic clamp. Works around a radial fan duct upgrade. Dependent on your fan and hot end box sizing, you might need to add 0.1 or 0.2 mm on the inner to make it a nice tight fit.

Model 4 changes: The tab to the right compensates for the different level of the side fan and the additional slots allow more air in to the front. Also the sides have been thickened very slightly (0.3mm) and now it is a perfect fit with no wiggle.
