Dome Drive Gear

I was unhappy with the performance of the BaneBots wheel that moved the lazy susan for my dome, so I designed and 3D-printed a dome gear for R2 on the Dremel IdeaBuilder printer at work.

I had some initial quality issues withe the 3D-printed pieces, but that was my fault due to the fact that I did not properly level the build plate. Doh!

The gear was made from one piece that I printed four times. The four pieces tabbed together to make the whole ring. I then sandwiched it between two rings of Sintra to make it more sturdy.

I 3D-printed a motor gear so that it would fit over the 1/2" Banebots shaft on my Jaycar YG2738 dome motor. 

I have to say that I am very happy with the results, and the dome stops on a dime!







You can see a video of the dome drive in action also on YouTube:

Sci-fi Day Discovery World

I has taken me a while to update the blog, but here are some pics from the great time I had at Sci-Fi-Day at Discovery World in Milwaukee.

The R2 Builders Group had a dedicated space and there was an amazing array of Droids and other robots,  including Wall-E and a Dalek! The space was very nice as it had the droids roped off from the public, which cut down on selfie photo ops, but limited the amount of abuse the droids took at the hands of the curious and excited.

Also, it was my first time trooping as a Jedi with the Rebel Legion, and it was a blast! The kids were great, the other super fans were awesome and there were so many great cosplay costumes as well!
