LiPo XT60 cap (battery tag, protector)

[Original design](http://www.thingiverse.com/thing:1260761) was is good, however sometimes (maybe because of my printer) caps were too loose. I redesigned the cap from scratch using FreeCAD. I modified a bit wall, base thickness and increased inner cylinders diameter. Now every printed cap fits my XT60 perfectly (I have 3S, 4S Tattu 1,3-1,5mAh).

I would recommend to try different caps from thingiverse becasue I noticed that XT60 from different manufacturers fits in these cap differently.
