If you’ve ever used a pumice stone to clean hard water rings or mineral buildup in a toilet or porcelain bowl, you already know the problem:
it works great, but holding a bare stone is awkward, slippery, and hard on your fingers
This holder solves that.
It grips the pumice securely, gives you a comfortable handle, and keeps your hand well away from the business end while scrubbing. More leverage, better control, less mess.
Features
Fits common rectangular pumice stones (the Amazon link above is confirmed)
Comfortable handle for better pressure and control
Keeps hands away from abrasive surface
No hardware required
Simple, sturdy geometry

Printing Notes
Prints without supports
PLA works fine, but PETG or ASA are better if you plan to rinse it often
Infill: ~20–30% is plenty
Layer height: whatever you like; nothing fancy here

Use Notes
Wet the pumice before use (important for porcelain safety)
Works great on toilets, sinks, and other hard porcelain surfaces
Do not use on soft finishes or coated surfaces
This is one of those “why didn’t this come with it?” accessories. Cheap stone, 30-minute print, much nicer experience.
If you remix it for different stone sizes or add texture/branding, post it — utility prints love evolution.
