JST-HX Connector Tool

This thing makes it easy to disonnect the balance connector on RC Lipo batteries. It is a simple device that clamps in the slot between the male and female connectors on a JST-HX connector. For most connectors you just slide the tool into place and give a gentle tug. If the plug is really on tight you can use a rocking motion to wedge the male side out.
There are 3 versions, an 8mm, 6mm and 4.5mm. The only difference is how wide the tool is. The 8mm is good for 6S batteries while the other two are helpful with batteries that have fewer cells.
Printed with PLA. 25% fill but I used 4 layers for top, bottom and sides to give maximum strength around the jaws.
