Makita 18v battery internal support

This is a redesign of the makita injection molded part that supports the balance and power board in the older non-LED 18v batteries. This is sized to fit common balance boards found on cheap Chinese wholesaler websites. The boards I got seem to work well. This is designed to fit these boards exactly. The difficulty is that original bracket/support is too thick. The replacement boards are also much taller. I printed in petg-cf and it worked great. Needed supports on for the spring support peg. I needed to design this because I was trying to replace the cells in these batteries but found out that the balance boards were bad and needed new ones. Finding direct replacements are impossible, so I went with a knockoff. Seems ok so far.
