FrSky X-Lite 18650 battery caps (Robust Version)

UPDATE 18-11-25 - Updated design. More rounded transition. I think it looks better. Hi, I have tried caps designed by AndreR and I really don't like the "copper foil design". It is definitely not long lasting and even not simple to do right. I made a system that requires only copper wire or thin copper sheet if you want to do it fancy. FINISHING PROCEDURE (TEXT PART FOR PHOTOS): After both sides are printed (I uploaded only Left side, the other can be done by mirroring original part in repetierHost or other sw) you need to prepare four "P-Shape" copper wires that fits into the mechanism of the cap (you can see it in the photo.) It is necessary that this P-shape is not higher than 0,8mm. It Will help keeping the contact with the pads on the xlite side. Then you insert the P-Shapes in there and fit them well. Now you have to prepare the part with a battery spring and insert it in the side lines and bottom of the cap. Solder the p-shapes and battery spring part and you are almost done. To improve connection with radio pads, you should add a bit of solder on the touching part of p-shapes and make it smooth adding some rosin. Finally pour some glue around the P-shape Line and you are good to go. :) Good Luck with construction If someone make a video tutorial, I will link it here.
