Sudoku 15×15 puzzle

Something plain but unusual – a Sudoku 15×15.  I’m sure these must exist, but it occurred to me I’d never actually seen one.  So I made one.

The rules are as you’d expect: place 1 to 9 and A to F into each row, column and 5×3 bold-lined box.

There’s no need to make pencilmarks to solve this – scanning is sufficient.

If you try it out, good luck! :)
