10-inch 1U Cudy HS105 rack mount V2

This is a 10-inch 1U rack mount designed for the Cudy HS105 2.5-Gigabit Ethernet switch.

It allows the switch to be installed cleanly into a 10" rack system, making it a good fit for home labs, network cabinets, and other compact rack setups.

The switch fits very snugly inside the mount and usually does not require screws. However, printer tolerances may vary, so mounting holes for the original screws are included if you prefer a more secure installation. For my Bambu Lab P1S with PLA Matte, the fit clearance used in this model is 0.2 mm.

This upload includes the updated V2 design. During real-world use, I found that the Cudy HS105 runs very hot under load, even after I added heatsinks inside the switch myself. Personally, that still made me uncomfortable, so I revised the mount to support additional passive cooling in the hottest area of the switch.

In V2, the bracket is modified so that two small heatsinks can be attached to the hottest spot on the bottom side of the switch. This keeps the mount within the standard 1U height and still uses three rack mounting holes.

If the user wants even more cooling, there are also two similar heatsink mounting areas on the top side. However, using top-mounted heatsinks increases the overall height to about 1.3U and would require four rack mounting holes instead of three.

I also included two front panel thickness options:

• 5 mm front panel — this is the version I use myself and the one shown in the dimensional drawing RELI.733218.001DD

• 3 mm front panel — a lighter alternative

Features:

• Designed for the Cudy HS105 2.5GbE switch

• 10-inch rack compatible

• Standard 1U version

• Tight friction fit for the switch

• Optional screw mounting

• V2 supports additional passive cooling with heatsinks

• Two front panel thickness options: 5 mm and 3 mm

• Minimal material usage with good rigidity

The model was designed in KOMPAS-3D v24 Home version. Printed on: Bambu Lab P1S. Material: PLA Matte

Cooling recommendation (Important)

The Cudy HS105 runs very hot. I highly recommend installing small aluminum heatsinks on the 2.5 GbE transceiver chips and the main switching processor, like this: 

In my case this significantly reduced the case temperature.
