The Mechanical Unit Circle is a mechanical demonstration of the unit circle and its corresponding trigonometric functions. It uses internal gears and slider mechanisms to move the markers along the shaped tracks as the angle pointer is rotated. This was created for the PrusaPrinters 3D Contest: Everyday Life Necessities. This was one of the first-place winners, with the prize being a Prusa i3 Mk3S 3D printer.

As a hobby, Devin makes 3D-printed full-scale props for use with costumes or decoration. Most notably: Melia's World Ender from Xenoblade Chronicles, Shulk's Monado from Xenoblade Chronicles, and Misa Amane's Scythe from Death Note. All of these props are full-scale, multi-part props that utilize different materials, colors, and attachment hardware. They are sturdy enough to be wielded as part of a costume.

The Squeeze-Fan is a hand-powered fan that converts linear two-directional motion into rotational one-directional motion. It does this through a series of gears and a ratchet/pawl mechanism.

This is an entirely 3D-printed model of the MSL Curiosity Rover. This was Devin's first major 3D printing project that he undertook since getting his 3D printer in the Spring of 2019. It consists of fully functioning suspension, wheels, and other movable parts. It utilizes unique 3D printing techniques such as supportless printing and print-in-place design. Some of the parts were also post-processed via acetone smoothing.

This is a simple toy train that was designed to fit on LEGO train tracks. It uses mixed manufacturing techniques, featuring 3D-printed plastic for the majority of its construction, hand-cut wood for the cab, and integrated assembly screws.

The train has detailed modeling and functional components, including turning wheels, working connecting rods, working piston sliding rods, and a hidden chain-and-sprocket mechanism to sync the wheels.

All parts were designed to be printed without supports. The chain links were also designed to be print-in-place, so each link would not need to be assembled; rather, the entire chain is already connected and only requires one connection.

All parts were modeled and manufactured by Devin.

This is another simple toy train designed to HOn3 Scale (1:87). This project utilized resin 3D printing to get extreme detail on such a small scale. The wheels and connecting/sliding rod are functional, with the connecting rod being loosely fit into the piston and the wheels rotating with an axle made out of a paperclip.

All parts were modeled and manufactured by Devin.

The dispenser allows people who may struggle with opening manual pillboxes/containers to easily dispense pills. It also allows for easy organization, as the machine dispenses one slot for each push. This was created for the PrusaPrinters 3D Contest: Everyday Life Necessities.
