2.5" to 3.5" Hard Drive Adapter

thingiverse

Just a basic 2.5 to 3.5 adapter I designed up because I needed one for a computer I was working on. No frills, just a chunk of plastic with some holes. It'll print without supports if you print it upright (standing tall with the cutout at the top), but you may need to add a raft if you have low bed adhesion so it doesn't get knocked over.
