Customer Reviews
Still my go-to for CNC parts
I've bought from OpenBuilds several times, and they're consistently reliable. This time I got a BlackBox Motion Control System and a few Anti-Backlash Nut Blocks. The BlackBox was easy to integrate with my existing setup, just like my previous Sphinx CNC kit was. Shipping was pretty standard, about 4-5 days, which is what I usually experience. Their parts always fit perfectly; never had compatibility issues with their V-Slot stuff. It's why I keep coming back instead of trying other places.
Got my NEMA 17s fast
Ordered some NEMA 17 Stepper Motors for a small project. They arrived pretty quick, like within 4 days. Everything was packed well. Really happy with the motors, they're working great in my setup.
Good parts, slow shipping to Denver
I ordered a C-Beam Linear Rail and some Solid V Wheel Kits. The quality was good, exactly what I expected from OpenBuilds. My only real gripe was the shipping time; it took 5 days to reach Denver, which felt a bit long. Customer service was helpful when I asked about tracking, so that was a plus. Overall, good value for the price, but they could speed up delivery.

Share tips, ask questions & help fellow shoppers save more
Hey, thinking about grabbing one of their CNC kits, specifically the WorkBee. How long does shipping usually take to, say, California? Trying to plan out a project.
Does anyone know if OpenBuilds ever do sales on their kits, like the Lead CNC? Or is it mostly just individual parts that get discounted? Trying to save a few bucks if I can.
