Hey folks! Today I am gonna talk to you about some of my Fidget Spinners! Until this year I had never heard about these so called “Hand Spinners” or “Fidget Spinners”. Well after printing out a few frames that I found online I decided that I would design my own frame and see if I could get good or better results. Two frame designs in I found the design that I would keep and called my own. I used my Flashforge Creator Pro 3D Printer to print out some frame prototypes so I could check if my measurements were correct.

I am now comparing the spin types and the speed of two bearings: the first bearing is by Spitfire and they work well, good spin times and fairly smooth. The second bearing is by Bones and they are also good bearings, they spin smooth and for just as long. The only difference I can distinguish is that the Bones Bearings spin a little quieter and smoother than the Spitfire Bearings.

The Spinners show below are printed with Hatchbox PLA and to be honest I feel that the PLA material is far superior than ABS when it comes to Fidget Spinners. I’ve printed Spinners using both ABS & PLA, and I prefer using PLA for the Spinners. I have had way less stress fractures that you commonly see with ABS, the PLA also has a great surface finish.  Most of the spinners I’ve made spin for at least 30 seconds and up to a 1 1/2 minutes!  A lot of people don’t care that it spins for more than 15-20 seconds, well I prefer long spin times, so these work out for me and most other people seem to like this design as well.

Using my Flashforge Creator Pro 3D Printer I was able to make some custom parts for this FPV Quadcopter, one of which is a low profile spacer that allows you to put all of the electronics inside the frame including the ESC’s which makes for a super clean build as show below.

The Flight Controller is running Cleanflight but I might switch it over to Betaflight, I still need to look into the recent changes of both Cleanflight and Betaflight.

Its running:

• Skyline32 Flight Controller
• FlySky TH-9 Transmitter
• 2500mah LiPo Battery
• Carbon Fiber 250mm Quadcopter Frame (ZMR250)
• Power Distribution Board
• 2000kV motors

Soon I will be posting a test flight video of this aircraft.

The frame I chose for this build is an: LHI 210mm Carbon Fiber Frame : Overall I am very pleased with the quality of this frame, very sturdy and lightweight coming in at 70g with all the aluminum hardware. In the future I will be using my Flashforge Creator Pro to 3D print some much lighter spacers to replace the metal spacers that come with the LHI frame.

During this build all of the wiring was done in a minimalistic fashion, I would measure the wire bundles allowing just enough wire to go from A to B then add about an inch to allow for some slack.
