If you guessed that the design above is some $20 item that was cheaper to 3D print than to buy, you're correct! It's a replacement for a broken wheel in my family's dishwasher rack, a 3D printout of which is shown next to the original below. The original I measured with a micrometer and re-made in SolidWorks, including the ribbing, to save a little plastic. The new design runs fine even in the heat and humidity of the dishwasher, and has since been used to replace two different worn-out wheels. Doing the dishes has been more enjoyable ever since!
Above: design for a bookshelf-cabinet unit with built-in chessboard in SolidWorks. Parts include MasterCraft flush surface-mounted hinges, pine panels, oak panels, and carvings and lathings of oak 3-by-3s. It is designed to be built with no visible nails and to split into a cabinet and a bookshelf. Below: the same design, with slightly different parameters, made a few seconds apart thanks to SolidWorks's global variable feature.
Above: beveled and helical gears (helical is missing a place for a shaft) based on the ones inside a KitchenAid mixer.

Besides SolidWorks, coursework and experimentation have exposed me to Fusion 360 (such as the assembly of another person's parts I reconstructed below), to CREO Parametric, and to CATIA, as shown in the Computer Graphics Technology course portfolio.
Above left: a four-part assembly in CREO, including bolts threaded by the helical sweep function. Above: an arch in Fusion 360, made for ASME's certification. Left: a keyboard support, made for ASME's 3D printing certification and to replace the ones missing from the school's computer lab keyboards.
