The Trend & Hype. There’s been a sudden explosion of fidget spinner designs on sites like Thingiverse.com. Most of them use a standard 608ZZ ball bearing to spin freely. They can be purchased online and cost anywhere from $10 – $20, but you could easily 3D print and make your own for a few cents!Jan 11, 2017.
Can you 3D print a bearing?
A 3D model of a ball bearing is prepared to manufacture a ball bearing using a 3D printing method. A commercial deep-groove ball bearing (6004) is used as a standard model of 3D printed ball bearing.
What bearings are used in fidget spinners?
Hybrid Ceramic Bearings are the best choice for fidget spinners. They have stainless steel races (outer case and inner ring) and ball bearings made from Silicon Nitride (noted as Si3N4) or Zirconium Dioxide (noted as ZrO2).
What fidgets can you make with a 3d printer?

What is a 608 bearing?
The 608 is a 8 mm Ball Bearing that can be used in many rotary and factory automation applications. The 608 8 mm Ball Bearing Inner Dimension 8mm X Outer Dimension 22mm X Width 7mm is an open style ball bearing designed for high rotational speeds and high dynamic loads.
What size bearings are in fidget spinners?
For the most part, 608 is the “size” used for fidget spinner bearings. The actual dimensions of a 608 bearing is 22mm total diameter, 8mm bore and 7mm width. The vast majority of plastic fidget spinners out there to buy — or 3D print yourself — accommodate 608 fidget spinner bearings.
What bearing spins the longest?
Japanese bearing company NSK has built the longest running fidget spinner at 12 minutes or more. The design uses small, high-precision balls and a weighty brass ring to ensure smooth spinning and maximum centrifugal force.
What is a pop it fidget?
A Pop It (also known as Go Pop and Last One Lost) is a fidget toy consisting of a usually-brightly colored silicone tray with pokable bubbles, similar to bubble wrap, that can be flipped and re-used. They come in a variety of colors, shapes, and sizes, and are marketed as a stress-reliever.
What is the most 3D printed object?
”The elephant turns 5 today. It is probably the most 3D printed thing in the world, and definitely one of the most downloaded object ever. It has inspired many to try new things in 3D printing.”Mar 1, 2019.
Is 3D printing expensive?
3D printing can cost anywhere from $3 up to thousands of dollars. It’s hard to get the exact cost of a 3D print without a 3D model. Factors such as material, model complexity, and labor affect the price of 3D printing. 3D printing services can sometimes cost more than an entry level 3D printer.
How strong is 3D printed plastic?
In most circumstances, PLA is the strongest material used in 3D printing. Even though PLA has an impressive tensile strength of about 7,250 psi, the material does tend to be a little brittle in special circumstances. That means it’s a little more likely to break or shatter when placed under a powerful impact.
Can you 3d print bushings?
Plastic bushings made with traditional manufacturing methods are mostly made out of Nylon. 3d printing nylon can be enjoyable if it’s done right. Nylon’s unique properties make it an ideal option for bushings. If you have used PLA filaments, then you know that it’s sensitive to high temperatures.
What is the difference between 608z and 608zz bearings?
608z is single shielded and 608zz is double shielded. Same bearing other than that.
What are steel ball bearings used for?
A ball bearing is a type of rolling-element bearing that uses balls to maintain the separation between the bearing races. The purpose of a ball bearing is to reduce rotational friction and support radial and axial loads.
What is ZZ in bearing?
2 Z / ZZ – Bearing with a metal seal on both sides. Z – Bearing with a metal seal on one side, one side open.
Is ABEC 7 or 9 better?
ABEC includes five tolerances classes: 1, 3, 5, 7, and 9 with 1 being the widest and 9 the tightest. Thus, bearings with a higher ABEC rating have tighter tolerances, and that means better precision, higher efficiency, and the potential to accommodate applications requiring high speeds.
What does C3 bearing mean?
Internal clearance being C3 means that the bearing has room for expansion if needed between the races of the bearing, whilst holding the outer ring and moving the inner ring in a radial movement you will detect a little amount of play between the two rings. C3 means the bearing has more clearance than standard.
Why do fidget spinners have bearings in the arms?
Fidget spinners are essentially low-friction ball bearings. That’s it. When two objects press against one another, friction prevents them from sliding smoothly. Most fidget spinners have a ball bearing right in the center of the toy, which is what you’re holding as it spins.
How heavy is a fidget spinner?
