@Logo thanks! it is a thick high temp o“ring (from he Alivi8, which make it suffer more than this

). But another o“ring, like theofficial one for the shield, would work great.
A woodworker did the inner diameters and the basic tube form factor. I did the final shape (not too complex

) and corrections, since the woodworker did it as a secondaryfast work.
@sternit thank you! I could make carbhole for some of them, depending on how tight they are (since they are not perfect andit must have a proper closed position). I could make a couple of holes on the fins zone in some of them, to improve the disipation.
@Zagala thank you!
@HaggisHunter thanks! The Beech wood has a nice beige/cream color!
@phenomflowers Do you mean the top o“ring? I should take a look at the size of the stem walls, i“ll tell you. At first, when they were straight, the OD was 15-16mm, but i don“t know the actual OD
@tashian The pequia one is my favorite! It is like golden ebony

(it has a density of 1060 kg/m³)
If anyone can tell me what kinf of wood is the ???? i would be grateful!

It is hard but soft to touch and the visual texture has that kind of wood gloss that changes when youy move it.
And adding something: the palo santo smell is great! For anyone who didn“t know that wood, it is used to be burned in churches and meditation purposes cause its smell.
