I had to make this printable! Check out my remix for those wondering if this is 3d printable! -Enjoy!

Brilliant! Then I went to the blog and hit a time warp and lost three hours of my life! I came out of the warp completely satisfied and amazed! Wow! Now to crank up the laser and make one for myself!

I did the same thing late last night. Was up for hours!

This looks awesome. As a new owner of my first 3D printer, I would love to see A version of this, that can be built up on one. It is definitely beyond my current skill level (for now),

Brilliant, can you post the files as a .dxf please???

i got a .dxf
email me at lermanrafi@gmail.com and i will email it to you

and did you get .dxf ? I would love to have one as well so I can make one on my CNC. Maybe else I will trace it myself to DXF

Building one myself, i have cut the parts out of plywood 4mm works great!!

Interesting, I'm keen to switch up to Laser ply for the design as MDF is stinky and gunky, did you just scale it up and everything worked fine?
(I can't buy 3mm laser ply, it's all 2.6mm thick so scaling it down didn't work)

Great design but..... files are missing some parts? The lower ball return into the wheel is missing the rest of the second layer that is the guides the balls and retains them on the that lower race. There is one side of it but that's it an it's not symetrical so you can't just use 2 of them and make it work.

looks great. Trying to think of how to adapt it for 3D printing. I have always been a fan of marble machines. :-)

Obviously the ring lift and brackets would all work fine (the ring lift would be better because it would be one piece instead of 30. I think you'd need to 3D model the spiral first though although that shouldn't be too hard either. I don't have a 3D printer though or I'd give it a whirl
