Jumper T16 accessories

This is a set of mod and accessory parts I am designing for the Jumper T16 Radio transmitter.

I have a replacement battery door with improved ridges for grip while opening.

Also a modded turtle back 18650 battery pack that snaps in place of the door. This uses 18650 battery tabs, a xt30 female plug, a male and female 2s balance plug, and 2 m2 tapered head screws.
Parts for turtle back.
