For my 19" 1U home server I created a dock for my two 3.5" disks. The disks can be easily dismounted. The model consist of a dock and a frame on which the disk is placed. The frame is mounted to the dock.
I used 4m nuts and flange bolts for mounting the frame in the dock. For mounting the disk on the frame i used 3mm cilinderhead bolts. I printed in PETG.
The author marked this model as their own original creation.
