The Plate Mounting Planner is a free tool that helps you plan your MultiBuild wall setup before you start printing. Enter your wall dimensions, choose your Plate type — Octagon or Square — and select your preferred mounting method. The planner generates a visual preview of how your board will look and outputs a complete parts list with exact quantities, so you know exactly what to print. Whether you are building a 3D printed tool wall, a garage organizer, or a modular storage system, this calculator takes the guesswork out of planning.
