Re: My hookah and a half PICSSSS
ya the left one (blue) is the HorasC stem w/the Mya base, and the right is the Mya stem with a Horas C base. The Mya base has a smaller inlet hole so I just swapped out the rubber grommets and it fits great.
I measured the wall thickness of the Horas C base with engineering calipers and it was 1.75mm. The penny I measured was 1.5mm for comparison
