KWS Rack DesignerStart designing

For 10-inch home-lab racks

From rack measurements to a print-ready STL

Set the panel height in U, drop in fans and device boxes, and let the vents fill the space around them. KWS turns an evening of CAD, test prints and re-drilling into a part you can print tonight.

A 2U front panel from the designer: two 40 mm fans, a device window, honeycomb around both.

How it works

The designer walks you through the part in the order you would build it.

  1. 1

    Front

    Pick the rack profile and the panel height in U. Choose a solid plate or honeycomb vents, and set the mounting holes.

  2. 2

    Components

    Add fans with guards and device boxes, then drag them into place. Magnets and guides line them up.

  3. 3

    Body and export

    Add a shelf, supports, a cooling duct or cable holes. Download an STL that slices without supports.

Vents that work around you

The honeycomb fills whatever space your fans and boxes leave, with a solid rim where it matters.

Fit-test coupon

Print a thin slice of the mounting edge first, and check it against your rack before the full part.

Questions

Which slicers work?
Any slicer that opens STL: Bambu Studio, OrcaSlicer, Cura and PrusaSlicer.
What material should I print in?
PETG is a good default for rack parts that sit near warm equipment.
Do I need an account?
No. The designer works without one, and exports too. An account saves your designs and folders; accounts are created by the administrator.
What happens when I delete a design?
It moves to Deleted, where it can be restored. It is not destroyed straight away.
