ADS-B aerial base

A printed base to slide a small ADS-B aerial into for greater stability.
Like the one here, if I'm allowed to link to it:

These little aerials tend to fall over because of small footprint. This design allows you to slip aerial base into it and gives a bit bigger footprint (plus a bigger area where the lead is, which is often what seems to twist it and make it fall over).

It is designed with a "void" inside it. Pause the print at layer 12 (which pauses it at the END of that layer in Cura) and then drop some washers in there before unpausing the print to "entomb them". Check your slicer settings and washers carefully to ensure that doesn't lead to a head collision on printing!!! This extra weight helps add stability.

I printed in PLA with 15% fill and support (very light ones otherwise it is hard to remove in the small gap). In fact I found just partially removing them was good enough for a firm fit.
