The original version was 40mm inside and 66mm outside and it was too small. These measure 76mm on the outside. I made them in TPU because it is chemicals resistant, is tough, and holds up well in the water.
V1 - (the black one) has drain holes outside of the internal cylinder. When I installed it you could see the metal shower fitting below
V2 - (the white one) has more coverage
I create these designs to encourage people to try out flexible filaments or get some new interesting colors of flexibles. For info on purchasing samples of several brands of flexible filament, TPU for as little as $1.99 per sample see 3dprintny.com
We developed a great way to distribute cost effective quantities of flexible filament: Splash Spools. A generous amount of filament on a spool with a case so it's not flopping all over the place. Splash Spools store easily in a desk drawer, stacked space or even hang on a wall. Available on www.3dprintNY.com , eBay and Amazon. We stock NinjaFlex, Cheetah, Armadillo, EEL, Filaflex, Flexy2 and Flexy.
