4 Drive Raid Cage
thingiverse
(I designed this sometime in 2018 and I no longer need it.) I made this raid cage for an old case to convert a 3 x 5.25 drive inch bay space to a 3.5-inch x 4 hard drive bays. There are likely better methods out there but this worked for me. It uses one 120mm computer fan and the separate assemblies are held together with 5mm x 1mm magnets.
