SindriCAD - Free, open source parametric CAD for 3D printing

by•
SindriCAD is a free, open source parametric CAD app for 3D printing, with solid modeling, printable surface textures, and STL/STEP/3MF export. Public beta out now for Linux, Windows, and Mac.

Hey everyone! I built SindriCAD because the professional CAD software I depended on simply didn't run on Linux, and none of the workarounds felt right. So I built my own tool instead of bending my workflow to fit somebody else's. It follows the shortcuts and workflow that most makers already know from mainstream parametric CAD, so the learning curve should be gentle. It covers the everyday solid modeling toolset (extrude, revolve, loft, fillet, chamfer, shell, patterns), keeps a full parametric history so you can tweak a dimension and watch the whole part rebuild, and can press real printable textures like knurls and honeycombs into a surface. It exports straight to STL, STEP, and 3MF (including multi-color 3MF) so it slots into whatever slicer you already use. It's free and open source (AGPL), runs on Linux, Windows, and Mac, and no account is required to try it. It's still in public beta, so expect some rough edges, especially on macOS where the build is currently unsigned. Would love feedback from fellow makers and 3D printing folks here - what would you want out of a CAD tool built specifically for printing rather than engineering drawings?

 I want it to run on a toaster tier computer, and to not crash like solidworks.

And for the UX to make sense.

FreeCAD is getting better but their UI is a huge part of the steep learning curve.

Things that are obvious in solidworks or onshape are weird in FreeCAD

 I can't guarantee we are there yet, since we're in beta, but I will do my best to get there. :)

I'm going to be putting this through a trial of fire.

I'm on OpenSUSE rn, trying your rpm build

 Remember, it's in open beta, so expect bugs. But rest assured that I'm working on it. Please report bugs you'll find via the bug report tool down in the right corner of the app, or via github issues. :) You are the first one I've heard of that will install it on OpenSUSE, so might show up some bugs we haven't seen before.
