Cup-Holder E-Cigarette Cradle (iStick 40W)

Update 27/04/17 due to the heat of the last days, even if printed in ABS, the e-cig holder had shrink issues in the car. so I redesigned it, improved the comfort and the anchoring sturdiness. ---------------------------------------- first release I needed a e-cig holder in my car. so you can find my design. suggestion to improve its functionality are welcomed!
