Drain Removal Extraction Tool 1.5" IPS Shower / Bath - Plumbing

This is a tool which can be pressed or gently pounded into a 1.5" IPS bath / shower drain to facilitate removal if you don't have a tub drain removal wrench tool or if the legs to which a standard tool attaches are rusted through, broken, or damaged.

There is a type of reverse (left hand) threading modeled into the part to facilitate gripping as the tool is intended for removal only, not installation.

Photos show how the tool attaches and the situation it's intended to address.

The .stl included is explicitly 39.9mm at its smallest diameter and is tapered so that the maximum diameter is just over 45mm. This slight taper is designed to facilitate the part wedging itself into the drain, specifically a 1.5" IPS drain.

The hex on top is almost 40mm in terms of socket size, but you're really meant to use channel locks for turning. It's as large as possible on purpose for strength.

Important recommended print settings:

• Use PETG for good strength, that's what's shown
• I used 0.2mm layer height, I'm not sure how critical layer height is
• Use a lot of walls for strength rather than increasing print density
  • I used 16 walls with a thickness of 1.8mm each
• I recommend printing either on its side (~90 degrees) or 45 degrees off of straight vertical, that gives the largest possible layers perpendicular to the rotation, see images
• I'd print with supports

It can probably be scaled to fit other size drains.
