Box case hidden hinges M3x25 .STEP

3D Printed Box with Hidden Hinges This is a box I designed with internal hidden hinges. The hinges require just three M3x25 screws for assembly, and I’ve included covers to hide the screw threads for a cleaner look (to be glued in place with cyanoacrylate). For best results, I recommend printing with “normal snug” supports and carefully tuning the support interface settings to make removal easy. The box closes with a snap-fit lever mechanism, ensuring a secure and practical closure. I’ve also included the .STEP file so you can freely customize the design to your needs.
