Fidget spinner assembly tool

The craze has not died yet and we still see fidget spinners everywhere. We recently made one with woodFill and copperFill. You can read the original post here.

Two weeks ago we held an open house for family and friends who were curious about our new building. We did not want to let them go home empty handed and decided to print a whole bunch of fidget spinners. The idea was to print the body of the spinners with PLA/PHA and nGen and create added weight by printing with copperFill. The copperFill parts needed to be firmly placed in the body and with over a hundred fidget spinners to be made, we decided to make a small assembly tool:

Design by colorFabb

The tool is printed on the Lulzbot Mini with corkFill and woodFill. We used a 0.38mm layer height to give it a nice coarse look.

The assembly tool is made up of a top and bottom halve, held together by two M3 screws screwing directly into the print.

A spinner can be slid in from the side and the copperFill weights (or bearings) can be positioned from above. They can then be tapped in to place with a hammer using corkFill cylinders as a driver.

woodFill was launched in November 2013 during the London 3D Print Show and was our first special filament. Other natural filled special filaments have followed, like bambooFill (which we recently discontinued) and more recently corkFill. Our woodFill has been a hit from day one due to easy processing and its fantastic looks. Added bonus is that your print room smells like a wood shop when printing with woodFill.


The Lulzbot Mini is available at colorFabb. As Lulzbot’s official reseller we ship from stock. We offer free shipping in Europe and two free spools of filament!

The LulzBot Mini was built to work out of the box, with no complicated assembly process getting in the way of you creating. Operating the Mini is the same- straightforward software, easy to read documentation and an army of LulzBot enthusiasts eager to help out people getting started. This printer is not only easy. you will still find flexible, industrial strength capacity from this machine.

Fidget spinner

As anyone know who has a working internet connection, fidget spinners are all the rage right now. We have seen quite a few popping up on social media in the past few weeks. We could not stay behind and printed one ourselves:

We based our print on the fidget spinner design by gyroscope07 (original file here), but removed the holes on the ends. Why? Normally one can put extra bearings there to add weight. But we have used our copperFill filament at 100% infill to add extra weight to this print. How much weight? This print weighs a respectable 45 grams, which you can really feel when spinning the fidget!

Our metal filled filaments, copperFill among them, weigh up to 4 times as much as regular plastic filaments.

Our metal filled filaments are an excellent choice for fidget spinners. One wonders, Why buy one when you can print a superior one?

The cap is the Comfy Fidget Spinner Cap by iDevel3D and it was printed with woodFill with 20% infill. The combined printing time for these parts was 2.5 hours.

For this print we used the Lulzbot TAZ 6 which has an excellent reputation with our special filaments, like copperFill and woodFill. The ease of use and quality make it one of the go-to printers in our printlab. The print was made with a 0.12mm layer height. For post-processing we did some manual sanding and used Brasso as a final touch.

copperFill was launched in the fall of 2014 and it was our second metal filled filament, after bronzeFill. The red shine that comes from the copper after post-processing has made it a fan favorite ever since. As with our other metal filled filaments, the aesthetics and weight are the key factors for choosing this filament and these characteristics make it a perfect filament for fidget spinners, for instance.

There are several five star reviews for copperFill on our website:
