This model is in beta - print and use at your own risk. constructive feedback actively encouraged in the comments below. Two designs on different plates - one with n-type connecter [WARNING - THE TAIL OF NTYPE MAY FOUL with Battery - you need the short internal stem versions], with no room for clip or gps module - and an sma antenna version that includes space for gnss/gps antenna in the lid, as well as a clip (print clip on it's side for strength). The clip needs to be pressed (with some force/mechanical encouragement) before the outer case is screwed on. Design doesn't really work without the TPU gaskets as sans tpu, the charging port on the base won't line up with the usb-c connector. with the tpu, the outer case will need to be cranked on quite tight to line everything up. I used conductive adhesive copper foil tape to attach battery cable to the single protected 18650 cell - the RAK has overcharge protection built in, so the protected cell is only really required to prevent over discharge.
