This is a remix of https://www.thingiverse.com/thing:4786176 - Ultimate Parametric Rugged Box - Snap Closure by zx82net (specifically the 110x60x30mm version)

I found the the snaps on the front of the box too delicate and even when printed in PETG would easily snap off. This design removes the bottom half's latch teeth and widens and flattens the top one, making it far less likely to become damaged.
