Ludicrously Big Fidget Spinner

As My Entry for the Fidget Spinner Design Contest I wanted to take my Anycubic Kobra 2 Max to the Max!

The result is a fidget Spinner that is 430mm (17 inches!) wide, and weighs over half a kilogram and uses a 1"ID 2"OD Axel bearing. (pictures show dachshund for scale)

and I'm not only the designer, I'm a user! (I've been fiddling with this all day). I am an extremely tactile person so my decades of fidgeting experience have served me well with many features.

• The shape, holes, and hardware give multiple textures and places you can run your fingers around whether the spinner is spinning or stationary.
• Even though it's heavy it can be operated single handedly, holding a handle and spinning it with your thumb.
• Spin time is about 30 seconds
• The outer ring has M8-12mm bolts which can be adjusted. You can use this to either balance the spinner for smooth spinning, or purposefully un-balance it. this adds vibrations which is an extra dimension of tactile feeling. This can give some of similar features of a Ahm meditation where you can close your eyes and focus on the vibrations and how they propagate through your body.
• It is a silent fidget toy. I have had many clicky-pens taken away from me from annoying people by obsessively clicking them.
• The handles are designed to use a threaded insert on one end and a hangar bolt on the other. This means you can loosen and re-tighten the handle (another fidget mode) without worry that you will destroy the threads. (sorry, this is North America, so I could only get 5/16" hardware for the hanger bolt/insert, but the holes should also work for M8 hardware)
• It creates a significant wind that you can feel on your face while spinning
• The layer lines on the angle give a nice circular pattern when spinning.

Note: please be careful with it, it is heavy and can have a significant amount of energy keep it away from your face (and pets' faces) when it is spinning

Hardware required for assembly:

• Qty 8 M8-40mm Bolts
• Qty 24 M8-12mm bolts
• Qty 8 M8 nuts (I used nylock nuts, but normal should be fine)
• Qty 1 5/16-18x3" Hanger Bolt (I used https://www.homedepot.ca/product/paulin-5-16-inch-x-3-inch-hanger-bolt-carbon-steel/1000152356 )
• Qty 1 5/16-18 Threaded insert (I used https://www.homedepot.ca/product/paulin-5-16-18-x-12-mm-knife-inserts-zinc-plated/1000129445 )
• M8 Tap to tap the outside holes

Most assembly should be self explanatory. To install the hanger bolt into the handle, put a nut on the threaded end, and use a wrench to twist the other end into the handle with the smaller hole. Install the threaded insert into the other side, you may need to heat it up to make sure that it is aligned on center.

Print settings:

• Printed in PLA
• 0.2mm layer height
• 3 perimeters (minimum)
• 10% infill (I used Cubic infill)

Have fun and Happy Spinning!
