Crossfire/Buzzer Holder
Designed to keep your Immortal T fully vertical why flying at 30° of forward pitch with no nulls. This angle is great when going outbound and even better when coming back at higher pitch angle assuming you're flying above yourself and not below. This tail raises the antenna higher and well above the battery and quad to prevent LOS transmission loss while still keeping the quad profile relatively low. Put the active element up top and the ground tube friction fits in the slot. Buzzer pushes in like stock.
GPS Backpack
Designed to give good separation between your 868~915mhz crossfire and the 1.22Ghz GPS receiver. Can go on the front or rear velcro tie. GPS backpack is at a 25° to maintain a good balance of horizon parallel angle when rescue kicks in between rising to max/initial altitude and forward flight on return to home.

Crossfire/Buzzer Holder, print vertically with the screw hole areas against the bed and the narrow tail extension in the air. Supports fill in the gaps, make sure there are no supports in the hole for the Immortal T though.
GPS Backpack print flat as it is mounted on the battery. I used supports to bridge the very small sections where the thin velcro ties go through. Might not be needed but prevents sag and easy to remove.
Use a sharp exacto and some flush cutters to clean up the support removal as needed. Easy and fast print.
