You will need 8 M3x40mm socket head fasteners for the main box and lid, 4 2x25mm stainless steel dowel pins for the over centre latches. 2 M3x30mm socket head fasteners and 2 M3 locknuts for the handle. Apart from the handle all the fasteners screw into the plastic.
I used these dowel pins that can be found on Bambu Labs maker's supply section.

Internal dimensions are: L134mm W174mm H70mm. With lid H85mm.
External dimensions are: L180mm W220mm H95. With handle H135mm.
I recommend the latches be printed with a CF filled polymer or ASA,ABS @100% infill for strength and durability.
NB: All print files are in the correct print orientation.
No supports are required.
Happy printing.
