Parameterized Basic Allen Key Handle

I wanted a customizable version of [death4u's allen t-handle](https://www.thingiverse.com/thing:5224840) that would allow me to create handles for allen keys of any size.

Additionally, I wanted the allen key to be removable from the design, as it's quite easy to strip cheap allen keys.

This design is not meant to enclose the entire allen key like death4u's design; it's meant to give you something to temporarily hold the allen key with while you're using it.

Please note the design is meant to be a quick 'n dirty implementation of an allen t-handle; it ain't the prettiest hunk of plastic but it works.

EDIT 03/09/2022: I have adjusted the design so you can either print it in two halves and glue it together like death4u's original design or you can print just one half as I initially designed for.
