3D Printing Toolbox
Print cost and filament calculators plus STL utilities, right in your browser.
3D Print Cost Calculator 📌 Work out the real cost of a print: filament, electricity, wear and failure rate. Filament Remaining Calculator 📌 Weigh your spool and find out how many grams and meters of filament are left. Scale STL 📌 Resize an STL to exact dimensions or fix inch/mm unit mix-ups. STL Weight Calculator 📌 Drop an STL to get its volume, size and estimated filament weight and cost.
Maker tools that keep your models on your machine
Calculators for print cost, filament left on a spool and model weight, plus STL utilities that measure and rescale files right in the browser. Your STLs are never uploaded. Everything is free, works offline once loaded, and the reference numbers (filament densities, empty spool weights) are editable.
