    A portfolio of CAD models. Some have general utility, others are just exhibits.

    A 3D printable case for the ODROID-N2 single board computer. One single durable part that clips into the heatsink; no fastners required.

    This little part is a backstop for the Knape & Voght 1300 Series drawer slides. It can be attached to the end of either rail to prevent the drawer from being able to slide past the end and drop the bearing roller out of the channel.

    It can be fit into place by hand, then gentle tap with a hammer will secure the force fit.

    I had cause to mount one of these hoses under a table. If you do too, I've got you covered.

    It's compatible with the HPASC 1-1/2 NPT-42mm fitting.

    An electric dish scrubber prototype assembly. It features a tricky gearbox that reverses the brush's direction every half rotation.

    In highschool I participated in the FIRST robotics competition on team 125, the NUTRONS.

    This was a formative experience; I wouldn't be where I am without it.

    The mentors who freely gave hours upon hours of their time to teach me hold my deepest, sincerest, gratitude and respect.
