round solar panel mount for goosenecks

this is a mount for round solar panels  for goosenecks.
under the link you can find the goosenecks that I used to mount the small 5V solar cells. There should be enough space to also be able to solder blocking diodes.

the M8 nut of the gooseneck can be pushed into the part for a propper connection

the two parts a screwed together with short M3 screws.

print without support, use whatever Filament that makes you happy.
