server hard drive tray

i have a server blade that i use for PC but dont know what blade it its and dont have the hdd bays so i designed a simple one that is used for 3.5 hard drives the hard drives mount from the bottom and are slotted so it can be adjustable hope this can help out other people fix their hard drive bays

the sides that slip in the groves are about 18.20 mm
the overall width of the bay is about 107 mm
and over all length is just over 155 mm
hope these measurements help in deciding if you need it
