Description
This Bambu Studio project file contains three plates with editable fire extinguisher service verification neck rings designed for use in facility fire and life safety programs.
Each plate contains one neck ring model so users can easily modify the service years and then duplicate the ring to fill the print bed without having to edit multiple objects individually.
The rings are labeled “Idaho State University Verification of Service”, but the year values can be edited to allow the model to be used for many years into the future.
This system was created for a university fire and life safety inspection program managing hundreds of extinguishers, where having a fast visual verification ring simplifies inspection workflows.
The project contains three plates, each with a different neck ring size:
Plate 1 — Small
For extinguishers with smaller valve necks
Plate 2 — Medium / Standard
Fits most common extinguisher valve necks
Plate 3 — Large
For larger valve necks
Only one ring is placed on each plate intentionally so users can edit the year once and then duplicate it.
Material:
ASA recommended (extinguishers may be located outdoors or in warm environments)
Other filaments may work for indoor environments.
Layer Height:
0.2 mm
Infill:
100%
Supports:
Not required
Orientation:
Print face down on the build plate (text facing the plate)
This orientation produces sharper lettering and a cleaner finished surface.
Install the ring around the extinguisher valve neck during service to visually indicate the extinguisher has been inspected for the specified service years.
These rings provide quick visual confirmation during inspections, especially in facilities with large numbers of extinguishers.
