3.5" to 5.25" Drive bay adapters - Universal

thingiverse

Universal 3.5" drive adapters for mounting in a 5.25" drive bay. Upper row of holes are for floppy drives (for those of us who still enjoy that vintage grinding noise), while the lower row is for HDDs (SSD mounting plates can utilize both). Standard 3mm drive bay screws should thread directly into the plastic. However, if either the screw doesn't want to bite, or the hole gets stripped out, provisions for M3 backing nuts have been modeled in. To this end, there are two models: the plain Drive Rail, and the Drive Rail - Pockets. The pocketed version has nut capture pockets. Since the primary model has fairly long bridges, alternate models are also provided for easier printing with minimal-to-no bridging, but consume more filament. The models with less bridging are listed as "Easy," and should print nicely on just about any printer. Rails have been tested on two of my cases for fitment (Silverstone and Thermaltake), but there is a chance that they will not work with cases from every manufacturer. YMMV
