Samsung Bike Battery Mount for 40mm Frame

My 48V 11ah Samsung bike battery doesn't fit inside the frame, so I designed a bolt on bracket to go on the top bar. 2 x M5 bolts hold each 3D printed bracket onto the 40mm round frame then 2 more m5 bolts holds the bottom of the battery battery to the 3D printed brackets.
Its designed so the bracket cant be removed once the battery is keyed on to prevent theft.
