Made a new model which loads from the tile side instead of the window side.  This way, it can be mounted on the tower the same way it lands in real life.  It has to fly over the tower from the west & back up into the tower with the heat shield facing east. 

After many burns, the nose becomes an oily mess.  The highest temperature was found to be the top row of windows in the nose.  That gets to 100C.

Sadly, polymaker HT-PLA seems to be discontinued.  There are HT PLA's from protopasta, for 4x the price of normal PLA.  The lion kingdom impulse bought 1 last roll of polymaker which was still less than protopasta despite having $10 of shipping & taxes.  It's not likely enough for future plans but it might cover all incense burner improvements.  There was an idea of printing motor mounts & maybe even a motor out of it.
