Send your 3D models directly from SketchUp to SimplyPrint for slicing and printing

## About

The SimplyPrint extension for SketchUp bridges the gap between 3D modeling and 3D printing.
Model in SketchUp, then send your work to your printer in a single click - no need to manually export files, juggle SD cards, or open a slicer in a separate window.

The extension adds a **SimplyPrint** toolbar, an **Extensions → SimplyPrint** submenu, a **File → Send to SimplyPrint…** entry, and a right-click context menu option.
Pick **STL** or **3MF**, choose whether to send the whole model or just your selection, hit **Send**, and SimplyPrint opens in your browser with the model loaded - ready to slice, queue, or print.



#### How to install

Grab the extension from the [SketchUp Extension Warehouse](https://extensions.sketchup.com/extension/3053e2f3-0ac1-4bf7-b383-9fd66d44f339/simply-print-slice-and-3d-print) (recommended) or from our CDN as a backup. Either way it's the same .rbz file - install it in SketchUp using the steps below.
