I started designing a VTOL tailsitter, a small electric aircraft which takes off and lands vertically like a drone, but can transition to fly like a plane. More info is in the project's README, and it was inspired by MIT's tailsitter. If you are interested in this project at all, feel free to DM me! Some sessions may have been slow because it was my first time using solidworks.

The repository contains the README, .STEP and .F3Z (Fusion360 Archive) files, as well as .MD files with pictures and videos for build documentation. Some Github commits were done after the sessions were logged, because it was very distracting to upload proof to Github every hour, especially when exporting CAD files can take 15 minutes for large assemblies. However, my sessions all have ample scraps for build proof. Some of the Github commits also link to Slack messages in my session threads, as the files are too large to upload to github directly.

I finished wiring electromagnets and belt rigging for "replac3d", a 3D printer build plate replacing robot.

This is a mold for half of a table tennis racket, including the blade and the handle. The paddle is meant to be made from hand-laid composites, and the mold itself is to be 3D printed out of PETG material. The molds are split in half to fit a 3D printer bed, and the model of the paddle itself is traced from various references online. The repository contains the STEP and F3D files for the paddle and its mold.

I began designing a robot that replaces the build plate of a Bambu Lab P1/X1 series printer using electromagnets and steppers called "replac3d". I finished the extension assembly's structure (unpowered) today! Working on the powering part now. If you are interested in this project at all, feel free to DM me! The repository contains the README and the .STEP and .F3Z (Fusion360 Archive) files.
