The prompt
Design a case for SMD electronic components featuring 15 x 15 mm compartments, arranged in a 15-column by 6-row grid with a depth of 10 mm. Include a lid with an integrated hinge system and a secure closure that effectively seals all compartments, preventing small components—such as 0402-sized parts—from mixing. Incorporate a creative locking mechanism to prevent the lid from opening accidentally. The external dimensions should be approximately 245 x 155 x 18 mm. The design should be suitable for printing in PETG or ABS, featuring reinforced side walls (3–4 mm thick) and a slightly thinner bottom.
