This is a remix of a Cree LED Light Holder by user mussy (I could not tag this one for some reason). I have shrunk this down to fit the Olight 3t2 EOS flashlight. The fit is snug so if you don't like it, scale up 0.5mm - 1.0mm. I have an older FlashForge 3D printer that does not print as tightly as newer printers so it may print perfectly for you as is.
