• I include the source file sun-shield.scad in OpenScad
• exported .STL files for individual parts (preset for mounting rods with a diameter of 42 mm)
• preset .3mf files

Printed parts

1. First step measure mouting pipe diameter
2. Open source code in OpenScad and change line

   MOUNTDIA  =  42;

3. Change the parameter gradually from 1 to 3

   Part  =  1;

   then press F6 and F7 for .STL export this part. Other parts not depend to mounting pipe diameter.

4. After complete all STL parts you can start 3D printing with WHITE PETG filament. Sun-shield part nr 4 you print four times.

1. Take part number one, half part number two on it and screw three M3 screws.
   ATTENTION, keep in mind that you are working in plastic and you cannot use great force for tightening.
   
   
2. Attach the thermistor to the center of the 3D printed part number 3 with the binding tape
   
   
3. Thread the thermistor cable through the eye in the 3d printed part number 2, as in the picture.
   
   
4. Screw parts two and three together using three M3 screws so that the cable exits through the gap as shown in the picture.
   
   
5. Attach the cable to part 3 with a cable tie
   
   
6. Screw together all four 3d printed parts number 4, using twelve M3 screws
   
   
7. Finally, close by screwing the 3D printed part number 5
   
   
8. Attach the assembled shield to the mounting pipe using two plastic binding strips
