Free 4K model: realistic metal detector with weathered control box, tactile knobs, coiled cable and search coil - ideal for exploration, archaeology and adventure props.

Metal Detector

A clean, game-ready 3D model of a motion detector (PIR sensor), originally modeled for Roblox and exported as a GLB/GLTF 2.0 file. Ideal for security scenes, surveillance environments, escape rooms, horror games, sci-fi corridors, office buildings, or any interior level design project requiring realistic safety hardware.

This prop faithfully reproduces the classic wall-mounted motion sensor formf actor - the rounded plastic housing with a fresnel lens dome typical of passive infrared detectors found in homes, offices, and retail spaces worldwide.

Free to download and use. No attribution required. Great for hobbyists, game developers, educators, and 3D artists building scene assets.

Low-poly optimized with under 2 500 triangles - perfectly suited for real-time

A recreation of the Amercian Signal Corperation RM Rotational, 130 decibel siren. So, not to be confused with the ASC T-130 (T-128?!?!) This is the RM-130 or PN-20. ACA originally created the first designs for this siren a while back as a prototype penetrator or protorype preformance plus penetrator (I don't remember). 

The PN-20 is the older name before American Signal Corp's Rebranding of the siren into the common RM-130 name. 

Also, on the 3m Signals, I got time recently and started their modeling processes. And for the Siemens Smoke detector I need more refrence as to the insides.

these are my roblox clothes for my roblox avatars to be used on vrchat when people can download them for free.

includes: 
- troll detector glasses to detect infiltrator trolls in the group.
- anti-flashblind goggles should the trolls use anti-player flashblinders.
- balaclava for anonymity.

A recreation of the Siemens Smoke detector/signal Model OP-110. 

I saw some mounting diagrams online, I didn't see much on internals so this is just a not-so-hollow model. I put as much exterior detail as possible though.

by Kuutti Siitonen A metal detector consists of a control box an adjustable shaft dubious discuss and a variable shaped pickup coil.

The ultrasonic helmet-mounted scanner was designed in Blender with a focus on ergonomics and technical detail. I began by modeling the helmet’s base shape with clean topology, then added mounts for the sensor unit. For the scanner body, I combined Subdivision Surface and Boolean modifiers to achieve smooth transitions and functional openings. The UV layout was optimized for efficient texturing, while materials were set up to represent metallic surfaces and matte plastic. Final rendering was done in Cycles, using studio-style lighting to highlight the volume and functional details of the design.
