I print some largish 10-inch rackmount shelves in PLA. Adapted these brackets to help with potential cantilever droops for one of the network switches with PSU power brick included on the 10-inch shelf, but should be easy to adapt to others.
The support “shelf” extends 52 mm
back into rackmount interior from flush with rear rail, and about 52 mm
along face from rack rail’s inside edge.
Front rack to back rack rail spacing is 200 mm
according to design drawings.
Modifications
Started with FreeCAD document Rack mount holder.fcstd
from Simple 1U rack mount holder or shelf. Imported into FreeCAD 1.0.1 on macOS.
12 mm
in both the X- and Y- directions (into the interior of the rackmount unit)
The author remixed this model.
- extended the "Holder" and the *face plate* 12 mm in both the X- and Y- directions (into the interior of the rackmount unit)
- lowered the "Holder" component to be flush with bottom.
- extend brace to meet the "Holder" in its new position.
