About this 3D model
Built upon the Gridfinity Storage Box by Pred ( https://www.printables.com/model/543553-gridfinity-storage-box-by-pred-now-parametric ), this multi-box storage system allows effortless access to multiple storage boxes while maintaining their stackability. Additionally, the modular handle provides optional portability. The solution also includes optional mounting capabilities for wall installation using a French cleat, although this feature has not yet been tested. Technically, this storage system can be used with just about any kind of storage box due to the parametric design. The storage system is assembled using M3 button head screws and bolts. Most makers are likely to have M3 assortments readily available; however, for those who don't, the following kit was used during the construction: https://a.co/d/0gfEO0l . This kit has ample screws for a 4-tall storage unit with plenty to spare. However, if you build multiple units, you may run start to run out of M3x6mm or M3x10mm screws and may want to pick up those sizes individually. What do I print? A basic storage unit requires: A left side panel and a right side for each box being stored A back support plate for each box being stored, minus one. For example, if storing 4 boxes, you need 3 back support plates. A top plate. I recommend the solid top plate with handle holes. A bottom plate. I recommend the wireframe bottom plate. 2 feet (optional but recommended). Standard printing configurations should be suitable for all parts. No supports are required for any of the components. I printed all parts without a brim, but depending on your printer's reliability, you may find it beneficial to use a brim for added stability during printing. Note that almost all parts are printed with their external surface facing down on the print bed, emphasizing the importance of bed adhesion for a smooth surface finish. This also allows for the use of a patterned print bed for unique surface effects. Important - Multi-Level Side Panels Multi-level side panels allow you to print multiple side panels as a single, unified piece, reducing the number of components and screws needed. This design enhances overall stability and strength while utilizing slightly less filament (approximately 5g per level). Whenever possible, opt for multi-level side panels for increased efficiency. For general use, I suggest primarily printing the 2x side panels. I've included 3x and 4x options as alternatives, but they likely won't fit on most print beds. Additional Options Feet While not technically required, feet are a valuable addition, especially when using the wireframe bottom. They cover the exposed hardware and help prevent scratching any surface the unit is placed on. For a soft, malleable foot, you can print it in TPU with 10% gyroid infill. PLA and PETG are suitable alternatives if TPU isn't available or preferred. Attach the feet to the bottom wireframe plate using M3x10mm screws and to the bottom solid plate using M3x15mm screws. Handle The handle is a great option for portability. To incorporate the handle, you will need to print: Top plate with handle holes Handle 2 left handle mount 2 right handle mount The handle mounts are attached to the top plate using 8 M3x10mm screws. The handle itself requires 2 M3x30mm screws. The handle has undergone extensive testing with 4 loaded storage boxes, demonstrating considerable strength. However, I advise against using the handle with more than 4 boxes, considering that storage boxes can become quite heavy when fully loaded. French Cleat The option to mount the storage unit to the wall using a French cleat is available. However, as I haven't personally tested this feature, your input would be valuable. Please use caution when loading the French cleat mount with weight. While it should be quite strong, I haven't had an opportunity to fully test its strength. The French cleat mount is based on ¾" plywood (21/32", ~16.67mm). Please let me know if other sizes are required. Boxes full of hardware can get really heavy. You may want to consider using two French cleats. Alternatively, you can use the French cleat spacer to support the bottom against the wall, distribute the weight more evenly and reducing the strain on the mounting points. To utilize the French cleat, print the French cleat mount and attach it to the back. The French cleat mount is used in conjunction with the back support plates and is positioned behind them, without replacing them. Use M3x12mm screws in place of the M3x6mm screws typically used to secure the back support plates. You can use M4 flat-head screws to secure the unit to the cleat, if desired. The French cleat spacer is installed in exactly the same manner. Tip Prevention The back support plate offers the option of including tip prevention screw holes, which can be added based on user preference. These holes are not intended for wall mounting, as the back support plate is not designed for such a purpose due to its limited strength
