I am building a fidget spinner out of LEGO and need two parts to help it spin better while not being extremely loose. The only part I can think of that would work would be a Technic 1M Half Beam, but I don't know if it exists. Does that piece exist? If so, where can I buy it from? If not, do you know of any piece that would work just as well?

Here is a picture of my WIP: fidget spinner You can see in the middle where there are two spaces that I would like to be filled. Something the height of a tile would fit.

If I understand your question, you are seeking a spacer that can spin freely on a Technic axle. Essentially, you want a 1/2 bush that has a round hole rather than an axle hole. I don't believe that this piece exists in Technic.

The old Technic Hub/Handle (424) may do what you want, but it is thicker than a 1/2 bush:

Failing that, a minifig ring may work for what you need if you have one handy:

Feel free to post pictures of your WIP and we may be able to provide better suggestions if those don't work.


Now that you've posted a photo, I wonder if a 1/2 Bush might just work:



I've now had a chance to play around with some alternate designs, and the one that I like best simply replaces the 2x2 plate and 2x2 tile with this wheel hub (3482):


This is solid and has a nice feel in the hand. It gives you the flexibility to have this rotate as tightly or loosely as you'd like.

Some others like to just use an additional 2x2 round plate:

  • That hub would be way too large May 25, 2017 at 22:47
  • How many tiles thick are those rings? May 25, 2017 at 23:48
  • The ring is 1 tile thick. I wonder if a half bush would do what you need seeing your photo.

  • I have tried using the half bush, but that causes too much friction. I don't know if the ring would be any better May 26, 2017 at 13:33
