    Very good, thanks for doing this, very helpful. Once thing I did notice though, the mini bearing 5x10x4.2 in the STEP file, but website says it is 5x10x4. So two of those and the 3.9mm depth of the mini v-wheel and it's about 0.6mm difference ? is the bearing 4mm or 4.2mm ... thanks !

      Good question! I don't have one of the bearings here otherwise I would measure it. I can't remember why I made the CAD model 4.2mm. I'll find out and let you know.

    Just what I was looking for. Am using FreeCAD and the STEP file format works great there. This entire site/community is just what I was looking for. May be attempting to build a large 3d printer using linear actuator assemblies or may just use them to expand/improve a Creality CR-10, if it ever ships. Prices are great here and the support will be most helpful too.

    Very useful.
    Sad that
    a) the end-stop plates are missing (they have a serious design flaw and I wanted to design a modified verison).
    I'll have to meassure and design them myself.

    b) no constraints between the dozens of parts in an assembly get imported (may be the fault of Geomagic to not import them, may be they are not present in the design). So everything is floating around unconstrained.

      Which end stop plates are you referring to? I would be happy to include missing parts.
      Regarding constraints, the original Solidworks assemblies definitely have mates, but they are lost when converting to a generic format such as STEP. I don't know if it's possible, but maybe Geomagic can import Solidworks files?

    Awesome, thanks for this. You've saved me a lot of work. I can go straight to work on an assembly. You're a hero!

    Could be better. Major flaw the round in the profile of the extrusion are not accurately dimensioned to what actually exists. This problem has been present in most if not all 3D cad files I have opened. The issue is this if you want to print a part that slides onto an extrusion that part with big round corner for the profile will now interfere with the actual aluminum extrusion making that part difficult to put on or not good at all. Unfortunately I found this out the hard way and the only fix I have been able to implement is to remove all radii from all extrusion profiles.
