Tube Plug / Stopper

thingiverse

This is a little plug for the ends of tubing. It works best for tubing from 70 mm to 110 mm inner diameter. This was inspired by and meant to be a replacement for medical catheter plugs. If you use this for those purposes, please take precautions to properly sterilize this part, and be advised that it is a one-use item, due to it having so many fine crevices for bacteria to flourish after initial removal. Instructions Print with the smallest cylinder pointing up, and the pull tab pointing down. Print one at a time. Use supports and a raft. Use 100% infill to make it water and air tight.
