Print in place 4 x 18650 spring loaded battery holder

I will use this battery holder to charge my batteries using 4 x TP4056 or you can use 2 x TP 5100

I wanted to be strong and reliable so I print it in Sunlu Black PETG with :

0.4 nozzle 

0.2 Layer Height 

4 Perimeters 

5 Top

5 Bottom 

and it came out in 47.41 g

it uses @ 15 m of filament

and the main advantage is that the cells after connecting them is not lose even if you shake the support! the cells stay in place, they don't fall off

thanks to  K014  for the great design
