    Cool project from @Sonny Lowe

    Makersl Brass Fidget

    Toys & Games item created by Sonny Lowe

    Project Details
    • Machine Time: ~9 Minutes
    • Bit or Laser Size: 1/8" Carbide 4 flute Flat End Mill .375" LOC
    • Feeds & Speeds: Spindle Speed setting #1 on Dewalt DWP611 (~16,000 RPM) Roughing was 0.75mm DOC 100% step-over at 500mm/min. Finishing was 4.83mm DOC (full thickness), material removed, .1mm at 200mm/min.
    • Materials: 360 Brass Flat Bar
    I designed this fidget months ago, it was based on an example I saw on Pinterest. It was designed in OnShape, programmed using Fusion 360 and exported to my Mini Mill via the Grbl Panel. I ran this on my Mini Mill in about 9 minutes using the tooling, and speeds & feeds as listed in the description. The machined surfaces came out pretty smooth, very similar to the OB Fidget, I did however decide to polish not only the top & bottom (like the OBF) but the sides & groves as well..."it's a beaut Clark" ;)

    I adjusted the bearing hole diameter on this one, reduced it to 15.8mm, undersized, so I could ream it to insure a proper fit...the finished machined size was 15.75 (not too shabby). I also decided to use tabs this times, although they function as advertised I'm still not a fan. It seems regardless of what material I'm machining or what speeds and feeds I'm using, there is always a small uncut at the points of retract and plunge. If anyone can tell me how to get rid of these I'd love to know!?!?

    Here are a couple photos and another short video...it's a bit better than the OB Fidget vid :p I'll also attach the step file in case anyone wants to give it a try, just remember to adjust the bearing hole size to your liking :cool:

    I'll install the bearing and the Chicago Screw Set tomorrow, I'll post photos of the completed toy then...

    Here's the Brass Fidget along with another one of my Fidgets, it's made from a Jockey Wheel off a mountain bike derailleur, that is wrapped with bike chain...
