cooling fan shroud for ubitx.

Fan duct for Ubitx Radio. I recently acquired a couple of these fans and thought they would make an excellent fan for the finals on my Ubitx radio. You can find similar fans at Amazon, specifically this Radial Cooling Fan designed for 3D printers: https://www.amazon.com/Radial-Cooling-Extruder-RepRap-Printer/dp/B07KHNVXFG?keywords=fan+12v+cooling+fan+3D+printer&qid=1547561527&s=Home+%26+Kitchen&sr=1-6-catcorr&ref=sr_1_6 The case on my Ubitx radio is an Indian-made radio case, and I had to rotate the fan 90 degrees to fit it in. The original design had the main power switch located on the rear panel, which was a bit inconvenient. To make things easier, I installed a rocker switch on the front panel. To simplify printing, I divided the duct into two parts and used a 3D printing pen to bond them together. My Wesen brand 3D printing pen was purchased from Amazon for under $20. Using PLA to weld the two halves effectively secured them in place. I wired the fan to run continuously. Although it's extremely quiet, it generated a significant amount of radio noise in my receiver. I hope your squirrel cage fan performs better.
