Design an electronics enclosure concept

The case is often the last thing a hardware project thinks about and the first thing anyone sees. Kubikly makes a 3D concept of the outside of your device, with the body, screen, buttons, grip and feet sized around the board it must hold. It shows form and where things sit; it does not model what is inside.

Ideas you could start with

  • “A wall-mounted air quality monitor, 9 × 9 × 3 cm, with a small screen and one button”
  • “A handheld remote for a camera slider with a thumb joystick and a lanyard loop”
  • “A desktop case for a credit-card-sized single-board computer with the ports at the back”
  • “A sensor box for a garden fence with a sloped top to shed rain”
  • “A bedside sunrise alarm with a fabric front and a dimmer dial on top”

Start from the board, not the box

An enclosure is sized from the inside out. Before you think about the shape, collect the facts that fix it:

  • The board outline and the height of its tallest component, plus clearance above and below.
  • Every connector, switch, light and screen, and which edge or face it sits on. The ports decide where the openings go.
  • The battery's size, and how it is charged or changed.
  • Mounting: how the board is held (screw bosses, ribs, clips) and how the case closes.
  • Heat: anything that gets warm needs a way for the heat to leave.
  • Radio: metal and some coatings block wireless signals, so antennas usually sit behind plastic.

What the concept shows and what it leaves out

The concept shows the outer form and where the visible parts sit: body, screen, buttons, grip, feet, a strap loop. That is enough to judge size in the hand, where a thumb falls, which way the ports face and how the device looks on a desk or a wall.

It does not model the board, screw bosses, clips, snap-fits, threads or gaskets, and it does no thermal or structural analysis. Wall thickness, draft angles and parting lines appear in the brief as points to check with the manufacturer, not as validated values. Electrical safety, radio and ingress protection are properties of the finished product, tested by a laboratory.

Enclosure concept in Kubikly, step by step

  • Choose Describe it, or Upload a sketch with front and side views marked with the port positions.
  • Set the kind of product to Electronics enclosure and enter the outside width, depth and height in centimetres, worked out from the board size plus clearance.
  • List the visible parts and where they go: “USB-C on the left edge, power button on top, 5 cm screen centred on the front”.
  • Describe a variant to compare, such as “a version with a rubber grip around the sides”, and switch between the two.
  • Export STL (4 credits, in millimetres) and print a form study to check the size in the hand or on the wall.
  • Download the part list CSV and give it, with your board's own files, to the CAD designer who will build the real housing.

Printed and moulded enclosures are different designs

A 3D-printed enclosure for a small run tolerates uneven walls, sharp inside corners and no draft. An injection-moulded one needs consistent walls, draft on vertical faces, generous radii and a parting line the moulder can work with, and its tooling is a large cost up front compared with each part. Decide early which you are designing for and say so in the brief: “first units 3D printed, moulded later” raises different open questions from “moulded from the start”.

Frequently asked

Can Kubikly fit the enclosure around my PCB file?
No. It does not read board files or model internals. Give it the outside dimensions you need; the CAD designer fits the housing to the board using the board's own 3D data.
Does the concept include screw bosses and clips?
No. Threads, snap-fits and internal fixings are not modelled. The concept settles the outside; the inside is designed in CAD.
Is the concept waterproof or certified?
A concept has no rating or certification. Ingress protection, electrical safety and radio approval depend on the finished product and are established by testing.
What does an enclosure concept cost?
Your first concept on a verified account is free. After that it is 10 credits on Normal (20 with more than one image) or 25 on Elite; an STL export is 4 credits and needs a credit purchase or a paid plan.
