Sentinels Symbol

In making a desk stand for my Orange Sentinel Lightsaber. I'm looking at woodburning a Sentinel Symbol on it, had anyone seen an honest symbol I could use?
TIA

A variation on the ouroboros might be good. Like stepping between the snake such that it only can eat itself, leaving no footprint by stepping in the spaces naturally arising...... as it denotes the "formless disorder that surrounds the orderly world and is involved in that world's periodic renewal". Plus, it was the symbol of the Envoy's from Altered Carbon and they seem a bit Sentinel esk
