three shells and how to use it

this is a remix of my [Anemometer Rotor with magnet mount](https://www.thingiverse.com/thing:4847579/ "Title")

i was sad about destroying ping-pong balls so i made shell drawings almost like an eggshell yet bottom part is spherical and that part is 42mm in diameter

Thin shell has a 1mm rim and than shell it self is 0.5mm with 0.4mm nozzle extruding 0.5mm line with 0.15m layer height it is printable with some supports.


Both version needs some support

thin_shell is a 30min print if supports are minimal.

Shell.stl is nice and surprisingly durable
