Impossible Passthrough Spiral - Free to Sell

Here is an adaption of my  spiral cone fidget toy, a cylinder with an external spiral. It's got a super smooth action and is about 72mm tall. Feel free to print and sell, or just print and fidget.   These look great in multi colour silk inner with a black outer.   If you like it, gimme a thumbs-up, rating or better still a review. A boost would be the the dream scenario. Thanks Did I mention, It's free to sell.  I've designed a few more Passthrough toys. Have a look at the collection
