I made this Gridfinity holder to fit my Innokin “Cool Fire IV” vape. I guess very few people have that model but I really love the size so I've had it for years.
It might fit yours too - main body of vape with battery is 24.8mm at its widest, which is where it sits on the Gridfinity holder. Mine is 85mm long excluding tank, but it would work with shorter or longer - see the pics and make a guess.
To be honest the main body of the vape isn't fully supported by the stand part, it seems to be held in by the little wings only - I could have made the wings a bit wider as the dimension seems a little under 24.6 but it feels very secure like it's not going anywhere.
