Spinning Top with Articulated Arms

Really cool idea!

Only complaint/observance would be that it wouldn't be the greatest spinner as it would lose some of its angular momentum after it got up to speed. This is because as the mass moves further away from the center of the spinning object it would take more energy to move that mass in the larger circumference it now has to follow. However, this is the entire point of the design, so I wouldn't call it a "bad" design.

I think it would be really cool if something like this would be made where those joints would fold inward once it got up to speed (i know it doesn't sound like it would be possible without some built-in servo/ motor in the print. However, if it was possible, then the spin would speed up after it got up to speed, thus making it spin longer.

Just food for thought.

Great top! Big hit with the kids! Printed great with a brim.

Glad they enjoyed it!

do you think it will be possible to print it without support (the base I mean)..?
I think my printer can handle that bridge..

The main base can be printed without support. I do recommend printing it on a raft or with a brim, which helps prevent the articulated arms from coming loose.

thank you, tonight I'm gonna print it!

Great, can't wait to see it!

Can't wait to make this - looks so fun!

Looking forward to seeing your Make! It's kind of mesmerizing, but I'm biased. My one year old son wants me to spin it over and over again :)
