Dell Optiplex Mount for 10-inch Racks

General Information

I produced this mount with a few design choices in mind.

1. I wanted the faceplate of the mount to better accommodate wider 10-inch racks.  The faceplate of the original model was slightly too narrow and the mounting bolts interfered with the faceplate.  I corrected this issue by copying the faceplate from this model.

2. I wanted the mount to fit my Optiplex 7050.  The original model had too much depth and the computer was free to move back and forth within the mount.  I corrected this issue by removing 2.5 mm from the total depth of the model.

3. I wanted the face of the Optiplex 7050 to lie flush with the front of the mount.  I implemented this feature by adding a 0.09" (~2.3 mm) lip.

Because I only have Optiplex 7050s, I am unable to verify fitment of other Optiplex micro models.  If the total depth of your Optiplex is 178 mm, then this mount will work very well for you.  Please comment with your model number and I'll create and update a compatibility list.

The mount prints well in a vertical orientation (faceplate on bottom; see .gif in photos) with the print settings below.

Print Settings

I printed the mount with a cube shape modifier (see diagram in photos) to increase the strength of the mount at the ears with the following settings.

The general settings I used were the default OrcaSlicer settings for 0.2 mm layer height with the following settings changed.

I changed filament color part way through the print for no other reason than reducing my white filament usage.

Assembly

Insert computer from the back and affix the back plate with four M4 screws that are shorter than 30 mm.
