1. I had a sudden idea to make a mini storage cabinet to store my fishing accessories and hooks. The boxes I usually use are laid flat, which takes up a lot of space when there are many items. So I thought about making an upright one to place on the desktop, and that's how I made this storage cabinet;

2. Making this still requires a bit of manual skill because the box is too small, and 3D printing materials cannot be made too thin, so the ejecting mechanism inside can only be made of metal. However, it's very simple, requiring only a small piece of steel wire and a 0.4*5*15mm spring;

3. The model is made quite compact, so pay attention to material shrinkage and deformation during assembly. I used Bambu Lab's PLA. If you encounter friction between the box and the ejecting mechanism during assembly, causing the box to not move smoothly, you can slightly reduce the height of the ejecting mechanism before printing again, or sand it down, or even trim it with a blade. Currently, the main shrinkage issues I've encountered are at the edges of a few cabinet compartments, mainly due to warping. Please pay attention to this issue when printing;

4. Installation steps:

      (1) Prepare the hardware by coiling the wire. You can buy 0.6mm thick steel wire, steel wire! Steel wire!! Only steel wire has elasticity. For bending, refer to my actual photos; it's just a few right angles, not difficult. Regarding dimensions: I've marked the small cabinet with a wire groove and a dot. The steel wire needs to be inserted into the wire groove. Bend it first, then insert it. The final length should not exceed that dot. The bending technique is to use pliers to bend right angles, then use pliers to hold and insert it. The bent end at the dot should not be long; just trim it to 1mm. It doesn't need to be very precise, just a bit short is fine and easy. If it's too long, it won't go in; short is not a problem, but long is;

      (2) After printing, first glue the springs into each compartment of the cabinet. The position should be roughly in the middle of the compartment; it doesn't need to be very precise, that's fine. Use tweezers to hold the spring, apply some glue, and place it at the bottom; it will stand upright. Just leave it until it dries. Regarding the springs, besides the 0.4*5*15 mm ones I used, in principle, as long as the wire diameter is 0.4mm and the length is 15mm, the diameter doesn't necessarily have to be 5mm; it can be up to 10mm. If you don't understand what I mean, just ignore it and buy the size I used;

      (3) After the springs are glued, glue the ejecting mechanism to the side of the compartment, with the pointed end facing outwards. But pay attention here!! It's recommended to place it in first before gluing, then put in a box with hardware to check if it fits. There are basically no issues. When I assembled this set, I only encountered a slight warping problem on the edge compartments during printing, which caused some compartments to deform. The solution is simple: you can just sand down one end of the ejecting mechanism;

      (4) There shouldn't be anything else to explain. If you have any further questions, communicate in the comments section. I have already explained it as detailed as possible.

3. Steel wire bending effect: This is after bending, the bent length is a bit long. It needs to be trimmed shorter after actually hitting the box. The image below shows it after being trimmed.
