The author remixed this model.
i changed the heat serts to take the 3.8mm heaatserts, I had tons laying around and could never use them, they come in the packs of heatserts you get from Ali, and are smaller OD but still take aan M3.
I also removed the switch, as I have no use for it, if i need to turn it off i'll just remove a battery and changed the antenaa output to take an SMA cable. Otherwise its all the same.
