Things I've Built

MakerX 3D File Sorter

Free Windows app that sorts a messy folder of STL, 3MF, STEP and ZIP files into categories with one click, with a built-in 3D preview and print estimates. Runs locally.

Print Analyzer

Drop in an STL and get a 3D preview, a filament and print-time estimate, and a cost breakdown in one page. Runs entirely in the browser.

Filament Storage System

A stackable shelf for spools with a matching set of printed labels (top, side, insert and in-stack) so every spool is identifiable from any angle.

Cauldron Lamp

A printed Halloween cauldron lit from inside by a battery LED tea light, with a jack-o-lantern version of the same design.
