As in , closer to a final version.
The side gear is a nice touch, care to show more about how you made it work? I assume it freefloats, and doesn’t have an axle?
I added 2 more round layers below that is the nominal bottom of the original design. The lower of the 2 ( top center in attached) acting as both the bottom and middle layer. The layer in between ( bottom right in attached) has openings sufficient for holding 2 gears. The larger gear ( n=30 teeth) protrudes out the side. The smaller( n = 20 teeth) is the same as the ones in the layer above. I probably changed the scale and the gear ratios at some point. It is scaled / ratio-ed so that I can get up to 5 orbiting gears in the top gear layer without gnashing of the teeth.
The larger gear rides upon an axle made from a 1/4 dowel. This axle is held in place by holes in the round plate above and below. A dab of thin glue keeps the axle from migrating up or down. It is about 3/8 long. The smaller gear is runs on a separate 1/4 inch dowel axle. This axle runs through all the plates. It runs through holes in the new bottom and the old bottom and the old top. It also runs through the center gear on the tip gear layer and though the pointer. Turning the large gear, turns the center stack and thus turns the orbital gears in the top gear layer. The circles with holes are used to make the axle thicker on the way to the pointer and the top plate (not shown) has the center opening expanded to allow the fatter part to pass.
Probably not as good for a game counter ( hard to control the pointer) but fun for amusing bored hands. People tend to not put them down for a while after being handed them.
This topic just continues to inspire. Great ideas!
Thank you for sharing your modification. I just made one and the toothpick hole made it easy to line up the pointer. I subbed in a half inch size 2 brass screw for the toothpick in the final assembly, fits perfectly and keeps everything lined up.
Thanks so much for this! Just made one for my brother for Christmas and it works great. Did the gears in clear acrylic, painted the base black so they would show better. I probably should have flipped the images… hopefully that doesn’t matter too much… lol
My kids keep trying to steal it to play with!
this has gotten out of hand. the triple axis magic 8 ball/ oujai widget spinner.
Was about to ask why there was(awesomely) a donut on the spinner…then I saw its a ouroboros.
…I like donuts.
This looks totally amazing! I’d love to see it in motion if you have a chance to make a video.
Thanks for sharing!
I made a video for this previously, but forgot to post it here: https://www.instagram.com/p/BqqJOLThlOs
One thing I noticed is that the round dowel tends to slip when turning, even with super glue. Anyone tried making a square one instead?
anybody make one of an 80 health one? My friend loved this design but requested an 80 health one.
Thanks for sharing this! It’s printing for me right now.
Yep, made mine square ages ago. Works like a charm. Why wouldn’t you use square then you can make the whole thing with the GF.
