Export blender objects as separate STL files

Missing. Hello? Anybody home?

Good news everyone! Our blender addon for multi-STL export is back! We have updated the addon to blender version 2.93.0 - it should be fine for a couple of versions. The addon allows you to export every object in a blend file to a separate STL file. This is handy for example to export various parts of a landscape and architecture design to STL meshes to use in a simulation.

The addon also helps if you have multiple objects in a single blend file, that have a relation to each other but you want to - for example - 3D print them separately from a number of individual STL meshes.

Since we removed the obsolete download we had a number of people asking and - due to popular demand - we have updated the addon to the current blender main version - just download via the link below and install it as you would any other blender addon. After installation you will find it under File > Import-Export > Rheo STL.

Installation and Usage

After downloading the zip file, open blender and navigate to Edit > Preferences > Add-ons, select Install, navigate to where you stored the downloaded zip file, select it and click the Install Add-on button. Back in the preferences tab, click the check mark to activate the add-on. Depending on your blender version you might get a compatibility warning, which you can usually ignore. In case the plugin is not working as described below, let us know and we’ll fix it.

On windows computers, we have seen the situation where the addon is not displayed from within belnder when it is stored in the browser’s download folder. If you cannot find the downloaded zip from within blender, try to move the zip file to a different directory.

To use it, simply select all objects that you want to export and navigate to File > Export > Rheo stl. Select a destination folder and all selected objects will be saved as separate stl files.
