MikroTik CSS610 Rack Mount — Compatible with KWS

MikroTik CSS610 mount for the 10-inch KWS rack

I started building a KWS rack for my homelab and got a bit carried away. I wanted my CSS610 to fit in with the other modules, so I made this mount.

Designed to fit the KWS rack, using matching mounting positions and corner radii. The front panel and side brackets print as one piece, with openings for the Ethernet and SFP+ ports, LEDs, power connector and ventilation. The front is 3 mm thick, with two rack screws on each side.

Thanks to Ilan Kushnir (@ilanKush) for KWS. I'm still putting my rack together, and I can see myself making a few more parts for it along the way.

What it fits

MikroTik CSS610-8G-2S+IN in a 10-inch KWS rack.

Overall size: 253.2 × 44 × 45 mm.

Printing

The included Bambu Studio project is set up for an X1 Carbon with a 0.4 mm nozzle and PETG:

• 0.20 mm layers

• 6 walls and 6 top/bottom layers

• 40% gyroid infill

• Front face on the bed, brackets pointing up

• 100% scale, rotated 45° on the plate

• No supports; 5 mm outer brim with a 0.15 mm gap

My PETG Basic settings are 250 °C for the first layer, 255 °C after that, a 70 °C bed and a 10 mm³/s flow limit. Adjust these for your filament. The slicer estimate is about 43 g and 2 hours 27 minutes.

Screws and assembly

For the rack, you'll need four M5×10 button-head screws with an internal hex socket (ISO 7380-1). Check that this length suits your rack. To find them, search for “ISO 7380-1 M5x10 button head socket screw”.

For the switch, reuse suitable original side screws. Check that they engage properly without bottoming out. M3×6 is used in the CAD assembly, but I haven't confirmed that as the factory screw specification.

With the ports facing you, the SFP+ openings should be on the right. Tighten the side screws a little at a time, alternating sides. The front panel should stay flat; if it starts to bow, loosen the screws and check the fit. Check that plugs and SFP+ latches move freely before mounting it in the rack.

Files

STL, STEP, an editable SolidWorks part, a geometry-only 3MF and a separate Bambu Studio print project. The rack, switch and hardware models are not included.
