OpenBuilds YouTube Channel

Hello everyone.  We want to let you know that we have recently put together an OpenBuilds YouTube channel where we would be uploading videos that pertain to OpenBuilds Parts and Builds.  Please take a moment to check out the two videos uploaded, so far.  They are short, very helpful, and highly recommended.  The first two videos are the Dual V Wheel Kit and the Smooth Idler Pulley.

If you would like, subscribe to the YouTube channel so you will know when new videos are released.  We have also added these videos to the OpenBuilds Part Store under their relating Parts.

Please stay tuned for more videos to be released as time allows.

Thank you,
The OpenBuilds Team

OpenRail is Shipping!!!

Its been a long road of learning and discovery and we are happy to announce that OpenRail is on the way! 

Collectively we have put in 200 hours of work in the last 4 days of packing rewards.  This Kickstarter  journey has taught us so many valuable lessons that we will carry with us into the future. This Kickstarter opportunity has helped OpenBuilds grow into a full fledged open source hardware distribution company that will continue to grow and bring cutting edge open source technology at affordable prices to both the consumer and distributor alike.

The OpenBuilds team is very excited to see what new awesome creations you all come up with using the OpenRail system. We look forward to sharing and participating in these ideas. 

We have been very busy here at OpenBuilds HQ and have moved forward with new innovative ideas that will push the creative limits of what can be achieved when dreams are realized.

Stay tuned for more to come! 

We thank you all for your extraordinary patience and kindness throughout this campaign!

The OpenBuilds Team
