I was asked for a stand for an antenna at 11" high that looked like an expanded hollow-point bullet and this is my novice attempt. Not modeled after any specific round.

Print it either single or multi; not sure which wastes more filament: double supports or a small wipe tower. But if you go single then you'll need to glue the lead part onto the copper part. You also probably want a brim around the tips of the ‘petals’ on the lead/copper parts.

The two brass parts are large enough that they're great models to use adaptive/support cubic infill. No need for supports on the brass. The inner threads didn't print particularly well for me but as long as you remove the bad/excess strands then it should be fine.

Looks a lot like a palm tree tbh
