F3d files can fe found here :
I revamped the SnapLock storage boxes, transforming them into parametric Fusion 360 files. Additionally, I integrated a gasket for improved alignment between the two sides, and implemented a poka yoke mechanism to prevent incorrect mounting of the latches.
With the original model, I was surprised to notice that many people tend to assemble the latch backward, resulting in difficulty when opening it. In this new model, I've incorporated a small bump to prevent backward mounting entirely.
This is my first model using Fusion 360, I usually use Solidworks. Please be understanding if there are any mistakes in the model. Additionally, I have not set specific limits on the parameters but have provided minimum values in the comments. Should you attempt to go below these minimum values, the model may fail to reconstruct correctly, and I recommend restarting from the initial file.
I have created two versions: a single-latch variant for smaller boxes and a dual-latch variant for larger ones.
Furthermore, I have shared the STEP files for both models.
