Mark4 XT60 mount for any kind of mark4.  For examle it can also on 13inch drone ))

Filament: TPU 95A 

Note: XT60 needs to be cut from the side where the wires exit (I made a protrusion there so that I could then melt it with a soldering iron, but it’s not necessary), then insert the connector with the wires soldered to it at 90 degrees.
