    Nice set of parts. One question: Description says "Drawings are included for reference", but I don't see them in the (1.5) .zip file

    There are no teeth on any of the timing belt pulley models despite being labelled as having specific teeth counts.

    Is this intentional, if so what's the point? Otherwise, glaring mistake that needs fixing

    This is very useful - Could you do me a favor - I need the 250mm version of the Nema 23 V slot Lead Screw Driven actuator. The 500mm version is in the assemblies and I was hoping not to re-draw it. It is in the OpenBuild documents so I am hoping you have the translator for Sketch Pro to Solidworks which I do not have. Great Work - thanks!

    It is a great resource and I appreciate.
    One thing that would be useful is if the measurements were a little more precise because the wheels don't seem to be fitting the v slots when mounted to the plate(in Fusion), even if you rotate the eccentric spacer to the farthest position the distance between the wheels is a little bit too short for the extrusion to fit.
    I don't know if the dimensions of the wheels are too big, or the extrusion is too big, or maybe the wholes in the plate are a little bit too close(I suspect this last one is the problem)

    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.
