PORTFOLIO

Below is my 3D CAD portfolio. Although I have designed hundreds of different projects, I have hand picked the few that best highlight my skills and talent. These projects best show my wide range of abilities and, although they might not be the most technically impressive of the projects I have done, they are the projects that I feel most drawn to. Please navigate through the rest of the website for a near complete list of all my other projects!

AUTOMATIC SCREWDRIVER

This client came to me with a problem statement: it is tedious to screw in furniture and cabinets and some of the screws are hard to reach. With that problem statement in mind, I worked with the client to come up with a fully functional automatic screw driver design that has a head that can swivel 90° in one direction. The design is about 11 inches long about 2.5 inches in diameter. It has four rechargeable lipo batteries that are wired in series powering. The trigger is a variable speed (hence variable voltage) trigger with a toggle for forward/backward direction). The motor is a 12V DC metal gearmotor that has a top speed of 100 RPM. The 90° rotation is caused by 3 bevel gears transmitting the torque to the driver bit. There is a spring loaded mechanism in the joint to allow the swivel to lock into 6 different positions.

I created animated videos of this design functioning and the client is going to license this design to a company that is involved in this industry. This design is intended to be fully injection molded and screwed together.

GENERATIVE DESIGN PLIERS

This client, Ganco AI, manufactures and sells fishing accessories and they specialize in pliers. Ganco AI came to me with a very specific request: to transform one of their standard pliers into a generative design pair of pliers. I first learned Fusion 360s generative design tool in high school and I was excited to put it to a real world application.

Ganco AI provided me with step files of their standard pliers. I removed all of the structural material (keeping the bearing casing, the plier grips, the plier handles and the wire cutting feature). I added in all of the necessary obstacle geometry (where the computer is prevented from create structural material). Finally I worked with Ganco AI to figure out all of the forces the plier will be subject to. I ran dozens of simulations with multiple materials in mind until we landed on a final version which I post-processed and sent to them.

ROBOTIC ARM

The founder of a small startup hired me to design a robotic arm for a satellite adjacent concept. His idea was to design a satellite repair box that could latch onto existing orbiting satellites and repair them. He asked me to design a fully functional robotic arm that could fit inside a 175mm x 175mm cube, stretch up to X m and have gripping functionality. The founder intended to 3D print and prototype this idea so that he could apply for funding and send this repair satellite into orbit.

After doing research and discussing further with the client about his goals, I decided to prioritize modularity in addition to the obvious functionality and simplicity. I selected the different motors necessary for the application and ran torque calculations to see how small of a motor the design needed at each joint. After about 20 hours of design work, I landed on the final design.

The final design features 7 axis of rotation each with a NEMA stepper motor (ranging from NEMA 7 to NEMA 14) to drive the robotic arm movement. The arm was designed to be modular as each axis rotation is either a large joint or a small joint. Thus, though there are 7 axes of rotations, there are only 4 unique sub-assemblies (the base joint, 2 large joints, 3 small joints and the claw). This design is currently in the process of being prototyped and iterated by an engineer who is 3D printing and assembling my designs.

REUSABLE CIGARETTE LOCK BOX

This client came to me as an individual with an invention idea. He wanted to create a safe, portable and sleek storage for a reusable cigarete and tobacco. He wanted the lock box to have a 4 digit dial lock with a swivel cap (non-removable). His goal for me was to have a functional 3D printed version of this lock box so he could test it out and then injection mold the components for mass manufacturing.

The biggest challenge for this product was the dial lock component. I had never designed anything to do with dial locks but I was excited to not only figure out how they work but implement my own version in this product. After figuring out how these locks worked, I turned to sourcing the lock components (as I knew they couldn’t be 3D printed). I attempted to source components online but to no avail. I then ordered dial locks and took them apart to use the dial lock components in the lock box design.

The final design of the lock box has the 4 dial code as well as a swivel top (which gives the user access to the code reseting functionality of the lock). It has two compartments: the larger one for the tobacco and the circular one for the reusable cigarette. The circular compartment for the cigarette is spring loaded to give the user easy access to the cigarette. The design, although initially 3D printed and held together by screws (not visible in the render) was designed for injection molding.

HYBRID GRILL

This client came to me with a new concept for a grill that is able to be powered by gas and wood. The design is composed of 17 gauge stainless steel sheets that are bent and welded together. The top cook grate is able to rise up 8 inches using a hand crank, bevel gears and lead screws. The compartment below the cook grate is the wood tray. Below that compartment is the burner box with 3 gas burners. Finally, the last compartment is the ash tray that collects the wood ash and slides out for easy removal.
