Your files never leave your computer. Every conversion happens entirely inside your browser. No servers. No uploads. No accounts. No cloud. Your models, colors, paint jobs, and print settings are processed privately on your own machine and nowhere else. 💸 Completely free — forever. No subscription. No trial. No premium tier. Install and use it, always. 🖨 Three printers, one click Select your target printer from the panel — Snapmaker U1, Flashforge Creator 5, or Creality SPARKX i8 — and drop in any BambuLab .3mf file. The extension converts the printer identity, G-code flavor, bed dimensions, toolhead configuration, motion limits, and all machine-specific macros automatically. Switch between printers at any time; your preference is saved. ⚡ Auto-convert MakerWorld downloads Turn on one or more targets and forget about it. Every .3mf you download from MakerWorld is automatically detected, converted for each enabled printer, and saved alongside the original — no extra steps, no interruption to your browsing. Enable all three and a single download becomes three ready-to-slice files at once.
