try exporting the model using millimetres.
Inventor will do that.

Almost no current software is particularly happy with inches.
Pretty much only used in the united states and most software is written elsewhere.

Some slicers do offer the ability to change the default settings to inches, but then it'll probably just confuse the printer as that only works in millimetres.

You can keep mucking about with inches, but you'll find life a lot easier if you just use millimetres for 3d printing.
