Gbfans shop aluminium trigger tip

Does anyone have the inner diameter of the trigger ring from the shop? In millimetres if possible, I’m metric.

Looking to swap out a resin one, but I seem to remember having to widen the ID for my homemade acrylic tube which I think is 25mm

Thanks in advance.

Never mind, I assume it will fit the 7/8" tube that’s for sale also in the shop, so looks like I’ll be re-scratch building my wand tip with 22mm clear tube
