This is my Stealth Inhaler made from an old Ventolin asthmatic inhaler, some old e-cig bits & a torch.
I made this one to hold an 18650 Battery with a 510 atty fitting.
In hindsight I should have used an 18350 Battery to keep the dimensions of the Ventolin inhaler.
I only made this for fun but it works better than anticipated.
If I ever make another I will use a smaller battery & keep the aesthetics in line with the original inhaler. Do you think it could stop you being told you canít use that in here?
