Desktop Storage Frame | Aluminum Profile Structure Suitable for 3D Printing | Freely Combinable Frame

Since aluminum profiles are time-consuming to 3D print, I modified the style based on the 2020 aluminum profile structure, making it more suitable for 3D printing. 20X20 cubes, combined with connecting blocks, can form various frames that can be extended infinitely in length, width, and height. For the 2020 cubes, you can adjust the length to fit your build plate size by deselecting proportional scaling in the slicing software. In terms of details, I designed a fixed support infill in the middle of the connecting blocks - the 'central small square', as well as covers to make the entire frame more aesthetic and robust, pallet buckles for each layer of support partitions, and two sizes of partitions with grid parameters set, allowing for quick and beautiful printing of suitable grid partitions.
When assembling, note that the six square holes of the connecting blocks have tapered tolerances, and the 2020 cube will generally snap into place at the 15MM mark when inserted into the connecting block. If weight-bearing capacity is needed later, you can choose to print the central small square and covers, and install them as shown in the animation above. The partitions are set with a grid; if you don't need the grid, you can deselect it in the slicing software yourself. If you're unsure how to set it up, you can refer to my previously published tutorial video.
