Neck Pocket Template for Strat - any recommendations?

I picked up the MusicLily CNC Strat template from Amazon, it’s predictably not quite right.

wrong heel curve (it’s flatter than the heel curve of the neck) and wrong radius in the corners. It’s also slightly too narrow, but that’s less of an issue than the first two points 

would anyone have any recommendations in the UK for a Fender-correct neck pocket template? Trying to avoid waiting weeks for a Stewmac! 

Its relatively  straightforward to take the dimensions off any relaible online strat plans and make up a template in mdf - cutting out and then filing caregully for an exact match. And then you have your own template for future use. 

Thanks Pete, worked out well enough! Appreciated!
