Li-ion cells soldering jig-holder

I created this holder to hold the cells in place while I solder them, i was tired of having to use makeshift methods every time..so i design it!

I use this holder to make 21700 6s2p and 4s1p 18650  li-ion battery packs for my long range drone, 

In the file there is also a knob to accomodate the M5 nut, just print 4 of it!

to complete the construction u need:

#4  M5 hex nut, 

#4 M5x35mm screws (cut the head)

#4 M5 Ruthex insert. 

U can use also a threated rod if u don't have m5x35 screws, just cut at the right measure.

Max internal space 138x72 mm,  holder is 65mm in height.
