Not sure why I'm posting this here, because it's a bit of a one-off print, but if others out there happen to order the same aprox. 20mm x 20mm heat sinks, maybe it will be useful. I used a 40x10 noctua fan, but any 40mm fan should work. Mine is currently hooked up to an 8-AA battery holder, but will be hooked to a potentiometer via power poles eventually.
I made this because my power supply is 13.85v and non adjustable. after several minutes of FT-8 on Full power, my TXCO was hovering around 120f (49c) stock. With the heatsinks, fan and shroud, I'm seeing 105f-108f (40c-42c).
I used OnShape for the design and the link to the public model is below so others can remix or export to their preferred format it as needed..
