External drive rackThis rack holds external hard drives. Transferring files can require hours and this keeps them out of my way. I don't like laying the warm drives atop one another, plus they require less space when standing on edge. Slots are sized to fit my thickest drive, a WD 1 terabyte (the short one in front), with a bit of room to spare. Almost all my tools and machines are SAE/Imperial so I prefer that system but for the sake of international peace and tranquility this is a metric version...basically just scaled my original 3.5x3.5x2 inch STL up to ~89x89x53 "Blender units". Afinia print software can't tell the difference between them but evidently some others can. 80 minutes, 34 grams ABS using Afinia default settings (0.30mm Z, medium speed with a raft).
