Ergonomic inhaler topper

I made this basic more ergonomic inhaler topper fit on most commonly used inhalers used in the UK. 

It is more rounded and slanted unlike the other ones I have seen which in my opinion helps with ease of use as the thumb is not exactly the opposite of fingers and it being slanted helped to spread the load at least I do think it feels a bit easier.

For the smaller preventer inhaler, I made just a more rounded version that is flat as I did not seem to see much difference when it is that close distance.  

Prints without support if you have a textured bed it make using an inhaler even easier.

If anyone needs a different size I'm more than happy to make one for you I need to know the dimensions.

I'm planning to offer a bit more sophisticated version on eBay if anyone is interested and does not have a printer and I would also like to make a lever action one so it is even easier to use.
