STL Scale Calculator

Another tool I built because I needed it myself

This is the tool I use before every print. Select the scale your STL was designed for, pick the scale you need, and choose between eye-level or top-of-head measurement. Supports 15+ tabletop scales including Warhammer 40k, D&D, Bolt Action, Star Wars Legion, and Shatterpoint. Everything runs in your browser — no uploads, no accounts, no cookies.
