Anti crown

As requested by a Reddit user who hasn't provided any info on the required dimensions.

The inner diameter is 140 mm. The walls are 1 mm thick.

Available in two versions: “blank” as well as featuring the quote of Chloe Mitchell in braille:

I sometimes fear that I am misunderstood. It is simply because what I want to say, what I need to say, won’t be heard. Heard in a way I so rightfully deserve. What I choose to say is of so much substance That people just won’t understand the depth of my message. So my voice is not my weakness, It is the opposite of what others are afraid of.
