Shower drain

thingiverse

We've had a scorpion wander up through the bathtub's drain, so we designed this little guy to prevent any more from getting through. It works pretty well and fits a 40 mm drain. To get a really snug fit, you may want to scale it up or down by about 1%. This design prints well with a 0.4 mm nozzle or smaller - we haven't tested it with anything larger yet.
