Okay, I have to change that then. I think I made the text black in the current iteration. So, I will need to change that.
Edit: I have updated the color on the engraved text, and I have updated the main post.
Amazing design. Thank you. I just got my Glowforge and was looking for something to do as a test cut. It worked wonderfully and I now have an amazing marble machine. I performed the camera calibration before the cut and used the same draftboard so it has cool little Glowforge logos on it. Attached is a picture of the marble machine assembled.

Very nice! I like the GF logo on the back.
Did you run into any issues?
That’s what happens when you use up the draftboard you used for the camera calibration process…

That is one ambitious “test cut!” Looks great!
Welcome! You’re going to love your new Glowforge.

No issues on the first cut. I broke a few parts as they press fit very tight. Especially the large axle. I reprinted them and could not get the glowforge to cut through the draft board. I guess it absorbed a lot of moisture between cuts or something. That is the consensus on the forums. I set to make 2 passes and it made it through.

Interesting… I haven’t heard of anyone having issues with the long axle. How did it break? Was it while trying to install the gears on it?
Yes. The gears required a significant amount of force to push on. The axle collapsed under the pressure, likely due to some amount of torsion from asymmetrical pressure on the gear.

I would guess that draftboard would have among the least resistance to that sort of stress vs plywood or acrylic?

Thank you for the feedback. I have never had that issue.
Those gears do not need to be pressure fit. They just need to stay in place and turn with the crank. I might look at slightly increasing the size of the inner hole so they can be assembled more easily.
The second one that I cut fit smoothly. There was likely a problem with my draft board. I do not think there is a reason to redesign.

An thank you again for the design. It was such a fun build, and my wife likes the glowforge now after seeing what it can do.

I love my Glowforge too! This is the first design I have drawn myself. I am still learning quite a lot and have been through several iterations with it!
I hope to come up with even more and continue to post them here.
I finally was able to build one of these! It turned out perfectly! I had some 1/2" balls and they work.
BTW, smaller balls also work fine. I have some 5/16" and they also work fine!
Thanks again for a wonderful design!
PS: I made mine with PG Maple.

Thanks for the pictures; that looks great in the PG Maple! I should try to create it from some of the plywood I have.
Did you have any issues or suggestions?
I was thinking about raising the inner rails to match the outer rails. But, that would just be for looks, not for functionality.
It’s really great as is. I can’t think of a thing that I would change!
I had zero issues with cutting or assembly, other than my own dumb thumbs from time to time! I did use a dab of super glue on a few spots, just to make it more durable. But I really don’t think anything needs to be tighter.
It was a very enjoyable build! I now have one more to make for my other grandkid!
Thanks again!

Second that! I cut one and got it all assembled, only to realize I have no marbles. But I have some coming tomorrow, very excited! I also had to glue a few spots but it seems really solid! Thanks for the file!

Can you tell me where you had to add glue? I don’t plan on changing the design for that, but I am curious.
On the top rail where it connects to the side with the crank, and then on the top rail on the other side connecting to the front. I think that was the only two places, everything else fit really well! Hopefully I put it together right, I’ll find out tomorrow haha.
