External Hard Drive rack

i designed this external hard drive rack for my seagate expansions as well as my seagate internal drive, it supports cooling with a fan of 80mm 24v and it protects your disks from vibrations and dust, i have uploaded the original files designed in sketchup if you wish to make modifications before printing, ive used my ender 3 classic to print the rack and the clearing was 0.25mm on each side so bear that in mind*
