OpenBuilds V-Slot™ Modular Framing System

V-Slot is an Open Source, high quality extruded aluminum profile building block that has an extremely smooth linear v groove rail on all 4 sides. It's precise, easy to work with and allows you unlimited design control through it's modular nature.

V-Slot's building characteristics are much like traditional T-Slot but V-Slot then goes on to add new levels of functionality through it's internal v grooves that allow for linear motion.
V-Slot is compatible with readily available, off the shelf, T-Slot components!

OpenBuilds™ Parts are now available in many easy to use and share formats!
Including STEP / IGES / SolidWorks / SketchUp Please see the OpenBuilds Parts Resource section here to grab'em. http://www.openbuilds.com/resources/categories/openbuilds-parts.5/
Thank you and all the best with your builds!

Example builds

V-Slot easily and quickly allows for creating mechanical assembly's and motion control systems for just about any type of platform you can imagine!


UPDATE - New file to download. SketchUp model includes examples of OpenRail mounted to the V-Slot Framing system. As well as the latest plate and wheel models. Enjoy!

Building with V-Slot is much like working with lumber.
You can cut it with a chop saw, and simply just bolt together using a screwdriver. And it is compatible with readily available T-Slot components.
"V-Slot can be used for most projects, such as 3D printers, CNC engravers, laser cutters, camera sliders, robotics and furniture. It could increase functionality of your design and drive down the cost of projects as well as the assembly time."

Download the SketchUp model files to design your own machines before you build them.

Is there any way we could get the models in STEP format? Getting SketchUp to export to a format that is usable in other applications is a flippin' pain. I want to use V-slot in some of my designs but I refuse to fool with the nightmare that is SketchUp.

We have bent a rail in a 90 using a conduit bender. It works, but the bend curved over as well so it would have to be done with a better means of keeping straight as it was bent. I think a 3 wheel gantry cartage would work great for this as well, having the single wheel side on the inside of the curve.

Has anyone used these to do curved motion? If a rail had a gradual bend would the carriage still be able to travel along it?

Your more then welcome Justin. Also for the latest versions of all the models please check the parts resources of OpenBuilds.com

thanks for posting the models here.

Awesome. Looking forward to seeing it. Thanks

Stoked! Decided to build my next bot with V-Slot. Thanks for the awesome product and I will definitely be posting a "Made One" soon enough.

Nice looking forward to the build gopedunderground! Please share on http://OpenBuilds.comOpenBuilds.com too when your ready :)

Good stuff folks!

Thanks Robaktime

You rock! Thanks for the response and good work :)

Hello JNR & kinnishian. We have a couple of volunteers working on additional file formats. We will post them when they are available. We are uploading the drawings to the website in the meantime. We apologize. We thought they were already there. Hopefully, this will help!
Thank you,
OpenBuilds Team

I second this (JNR's comment). Would appreciate more universal file formats. Are there any options like STEP or something I can convert to Autodesk Autocad files?

many thanks.

Hi, very great idea, and I very appreciate the open-source way decision. However sketchup isn't the ideal thing tho share the components' measures. I use CatiaV5 and SolidWorks, i Tried to export from sketchup to dxf and then import in either Catia or SW to re-design at least the 20x20 V-Slot framing, but inaccuracies appears. Can you post blueprints with dimesion please?

Yes, the OpenBuilds Dual V Wheels are compatible with both V-Slot and OpenRail. Thanks!

Does this use the same V wheels as the openrail system?

I can't wait for this. It'll be much better for the scanning rig :D

Thank you flurin for the tip
SketchUp version 8. No reason really just what I have loaded :)
Thanks again look forward to seeing your next machine design

I'm looking forward to design my next machine using V-Slot.
