About Rapid Elevation
A free toolkit for FDM 3D printing, built by a maker who got tired of hunting for answers across a dozen different browser tabs.
Hey, I'm Jake Lewien — an engineer and maker who has spent way too many hours troubleshooting bad prints. Rapid Elevation started as a personal collection of calculators and references I kept rebuilding from scratch. Eventually it made sense to put them in one place and make them actually good.
Everything here is completely free and runs entirely in your browser — no accounts, no tracking, no data leaving your machine. G-code files and STLs you upload are processed locally and never sent to a server.
The site is a work in progress. Tools get refined, new ones get added, and feedback directly shapes what gets built next.
