Micro SD Storage Disc

thingiverse

With all the micro SD cards in the camera bag, I needed a solution to keep them organized, prevent them from getting lost in crevices and provide an easy way to identify which ones were empty and which had been used. This led me to design a disc that stores 5 micro SD cards and allows tracking of used ones by flipping them over when putting them back in place. The built-in indexing mechanism prevents accidental rotation, stopping at the opening over a card slot for access and in between for storage. UPDATE: While printing more discs for my camera bags, I found the retention fingers were breaking off too frequently, so I made some design adjustments and added slot identifiers on the front to better distinguish between cards. Print Settings Printer Brand: Printrbot Printer: Printrbot Simple Metal Rafts: No Supports: No Resolution: 0.2 Infill: 30 Notes: I printed this using a 0.4 mm nozzle in ABS, ensuring the retention fingers were flexible enough for assembly. I also used a slightly higher temperature than normal, around 240 degrees Celsius, to achieve better inter-layer bonding - the retention pillars hold up well under these conditions. Additionally, I applied ABS Juice to get the first layer to adhere properly, similar to any ABS print. I printed the tops in PLA using the available filament color. Post-Printing To assemble this disc, simply snap the two pieces together. How I Designed This I created this design in Fusion 360 - a fantastic software tool that made it easy for me to bring my idea to life.
