I had to make this printable! Check out my remix for those wondering if this is 3d printable! -Enjoy!
Catapult shot is much cheaper than regular ball bearings presumably because it is made to a lower standard, but they still roll and I can't tell the difference

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!
Phew, I worry a little bit as my things are just files, minimal words and a link to my blog but time restricts what I can post here. Pleased to hear people enjoy my blog
Well I edited the file to recreate the missing return trough rails and printed it with adjustments for 2.8mm plywood. Works great. The only problem is the marble issue itself. Going to have to find a supplier for those. Regular glass marbles are far too varied in size and considerably larger.

As a previous commenter had noticed one of the lower ball guides was missing from the drawing. I opened it in illustrator and sized all the slots for 2.8mm plywood. Created the other ball guide. I'll let you know how it works!
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),
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)
if youre interested.. imkovb.blogspot.nl/2013/02/marble-machine.html this include's the design changes.
no scaling was needed, i did changed the plan's to fit lager marbels 16mm i can't find 9.5mm marbles. Also changed it so there is no need for metal parts and everything is lasercut. Ill try to cut the parts tonight and test them out. If it works ill post my modifications, if youre interested.
no scaling , i modifyed the plan's so there are no metal parts needed. i plan on cutting it tonight if it works ill post the plans. Needed to change the size of marbles since i can't find 9.5 mm in the timeframe i have. Easyer to change the design :)
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
thanks for the post! Your work is fabulous!
beautiful! really well done!
I received this kit for Christmas. Very cool.
beautiful! wish I had a laser cutter
Now is an excellent time to go and find your local hacksapce then
Why?
Wrong word: I said 'terrible' in the meaning awesome, impressive...
Think you mean Terrific!
Yes!
Had me worried for a sec, I don't mind criticism but I do like to know why :)
