Modular, customizable 3D printed storage inserts for knife collectors and hobbyists.

The user crafted a custom box for their pocket knives, highlighting the need for specialized storage solutions that aren't easily found. A comment pointed out a design flaw—difficulty in removing the knives—which the creator acknowledged. This opens up an opportunity for a product line of modular, well-designed storage inserts for collectors (knives, watches, pens, and more). These could be 3D printed, allowing for customization to fit different item sizes and features like finger cutouts for easy access. The product could be sold as physical prints or as digital files for users with their own 3D printers, catering to the enthusiast market that values organization and custom-fit solutions for their valuable collections.
