glock lower airsoft

could not find airsoft lower for g17 anywhere.
this is based on file for real steel lower and rough measurement of my airsoft g17.
please feel free to print/test/adjust and let me know the outcome.

it was done in tinker, im not a graphics design wizard so its a bit rough

added file with bigger internal cavity, still needs a lot of work but it is printable and it works
