Not only is this a fidget toy, but it is also a finger & thumb exerciser as well, handy for all you guitarists or trumpet players out there.

the idea came from a guitar finger exerciser but there is never a provision for the humble thumb so in this fidget toy I have added provision.

The Fidget toy is designed using Fusion 360 and printed in Bambu Studio with support from build plate only, there was a bit of stringing where the printer bridged the top of the slots but this was ok.

Printed with the BambuLab Carbon X1

On assembling the components I ended up using 2 springs(9.5 x 19.1mm) for each finger slot apart from the thumb slot where 1 spring was used and the internal thumb spacer thing had to be filed down for it to fit in the slot, or just use a washer or something, I used 3mm set screw approx 12mm long for securing adapters to the plunger.

Cool little project.

Thanks for looking.
