I made this for the fidget contest so it's really a “flash” design !

So, not so much for the looks!

So many fidget thingies already exist on this site and others (thingiverse) some are even commercially available; I hope I came up with something a little more original, but you know, big world, so you never know if it's not been designed already.

Before you try to print (it takes about 2.5 hours at 0.2 with no support if you place on face correctly the top and the choice plate), I would like you to look at the stl files and imagine what this thing does (even though, if you have read carefully, there should be a hint!).

The tricky part was the design of the PLA spring and its tuning. I believe I tried 5 or 6 different shapes and finally came up with this one which is springy enough but not too springy, I think.

It also produces a loud noise when making the decision (not quite like a gavel but the verdict comes anyway).

My other photo shows to those that are not familiar with design, that its not “a long fleuve tranquille” as we say in french.

Enjoy!

PS: in case you want to change the choice plate, it should be easy to design you own… (just saying for your makes)
