Custom Enclosure Design Services

This project focuses on the design of custom electronic enclosures optimized for 3D printing. The objective is to create enclosures that are not only visually clean but also functionally engineered for PCB mounting, cable management, ventilation, heat dissipation, and easy assembly.
custom electronic enclosure

Each enclosure is developed as a manufacturing-ready 3D model, considering real-world constraints such as printer tolerances, wall thickness, snap-fit behavior, and screw boss strength.

Design Considerations for 3D Printing

The enclosure is designed specifically for FDM / SLA 3D printing, with attention to:

  • Uniform wall thickness for strength and print quality

  • Proper fillets and chamfers to avoid stress concentration

  • Draft-free geometry suitable for both printing and molding

  • Optimized part orientation to reduce supports

  • Tolerance allowances for snap-fits and screw joints


Internal features such as PCB standoffs, screw bosses, and alignment ribs are positioned accurately to ensure secure electronic assembly.

This view shows the overall enclosure form, proportions, and how the top and bottom shells fit together.

Functional Features

The enclosure includes:

  • Dedicated PCB mounting posts

  • Ventilation slots for heat dissipation

  • Cable entry cutouts and connector openings

  • Snap-fit or screw-assembled housing

  • Clearance for components, displays, and buttons

All features are modeled parametrically so they can be easily adapted to different board sizes and product variations.

Manufacturing-Ready Output

Final deliverables include:

  • STL files optimized for 3D printing

  • STEP / SolidWorks source models

  • Assembly-ready tolerances

  • Draft-free, clean, watertight geometry

  • Optional 2D drawings for CNC or injection molding

Tools & Expertise

  • SolidWorks / Fusion 360 enclosure modeling

  • Design for Additive Manufacturing (DfAM)

  • PCB fitment and tolerance design

  • Snap-fit and screw boss engineering

  • Thermal and airflow layout concepts

If you need custom electronic enclosures that are ready for 3D printing and real-world use, I can help you convert your PCB or concept into a professionally engineered enclosure.

From first draft to print-ready files, I deliver accurate, clean, and production-focused CAD models.

Fluid mechanics VIVA QUESTIONS and ANSWERS

1. Define density? Ans: It is defined as the ratio of mass per unit volume of the fluid. 2. Define viscosity? Ans: It is defined as the property of fluid which offers resistance to the movement of fluid over another adjacent layer of the fluid. 3. Differentiate between real fluids and ideal fluids? Ans: A fluid, which is in-compressible and is having no viscosity, is known as ideal fluid while the fluid, which possesses viscosity, is known as real fluid. 4. What is a venturimeter?

Isometric drawings for practice in AutoCAD

What is Isometric Drawing? Isometric drawing is a method of visually representing three-dimensional objects in two dimensions. It allows for a clear and comprehensive depiction of complex structures by keeping the scale consistent and eliminating distortion. Isometric drawings use a 30-degree angle from the horizontal in all three axes (X, Y, and Z), creating a pseudo-3D effect where the height, width, and depth are equally foreshortened. Creating Isometric Drawings in AutoCAD AutoCAD provides tools and settings that make creating isometric drawings straightforward. Here’s a step-by-step guide: Step 1: Set Up Isometric Snap/Grid 1. Enable Isometric Snap/Grid:    - Type `SNAP` in the command line and press `Enter`.    - Type `Style` and press `Enter`.    - Choose `Isometric` and press `Enter`. 2. Switch Between Isoplanes:    - Type `F5` or `CTRL+E` to toggle between the top, right, and left isoplanes. Step 2: Draw Isometric Circles and Arcs 1. Isom...

Coordinate systems in AutoCAD

World Coordinate System (WCS), User Coordinate System (UCS). There is 4 AutoCAD coordinates system you should know. Absolute coordinate system , Relative Rectangular coordinate system, Relative Polar coordinate system and Interactive system(Direct coordinate system). Absolute Coordinate system: Absolute Coordinates uses the Cartesian System to specify a position in the X, Y, and (if needed) Z axes to locate a point from the 0-X, 0-Y, and 0-Z (0,0,0) point. To locate a point using the Absolute Coordinate system, type the X-value, Y-value, and, if needed, the Z-value separated by commas (with no spaces). Syn: Enter LINE command: L [Enter] Start line at point A: 0,0 [Enter] End first line at point B: 2,2 [Enter] End of second line at point C: 2,3 [Enter] Examples shown bellow. Relative Rectangular Coordinate system: After first points entered, your next points can be entered by specifying the next coordinate compare/relative f...

TIN SMITHY & Sheet metal

TIN SMITHY Introduction : Many engineering and house articles such as boxes, cans, funnels, ducts etc. are made from a flat sheet of metal. The process being known as tin smithy. For this the development of the article is first drawn on the sheet metal, then cut and folded, to form the required shape of the article. Allowance should be given in the drawing stage for folding and bending. This allowance depends upon the radius of the bend and thickness of the sheet metal. Sheet Metal Materials : A variety of metals are used in a sheet metal shop such as galvanized Iron, black, Iron, tin, Stainless Steel, copper and Aluminium. Hand Tools : The common hand tools used in sheet metal work are steel, try square, Wire gauge, Scriber, Ball peen hammer, Nylon Mallet, Snips Divider, Stakes, Cutting plier and Soldering Iron. Here, the details of tools that are being equipped by our workshop purpose only are presented. Wire Gauge: The thickness of sheet is referred in numbers known ...

Sheet metal Funnel making

Making a Funnel using metallic sheet Making a Funnel using metallic sheet Aim:- To make a funnel from a given (GI)metallic sheet. Tools Required:- MALLET, SNIP, STAKE, STEEL RULE, BALL PEEN HAMMER, STRAIGHT EDGE, RIVETS, SCRIBER Procedure:  The size of the given sheet metal is checked for its dimensions using a steel rule The required development of surface is being made on the white paper which is overlapped on the sheet metal. The marking is done on the sheet metal as per the development being done on the paper. Now using straight snips, unwanted materials are removed. Now fold and bend the workpiece to make the funnel shape and joint is made on the workpieces. Then using a groover, a locked grooved joint is made for about 5mm. Also, hemming is done in the bottom of the funnel. In between top face and bottom face, a butt joint is made using a solder. Finally, trimming and finishing operations are carried out.
