Radiation 3D Models: Signs, Shields and Props

This collection gathers radiation-themed STL files: hazard signs and markers, sensor shields for weather stations, decorative covers for 3D printer parts, and props from post-apocalyptic settings. Most of them are small prints that use little material. It helps to decide first whether you want a functional part or a display piece. Polyzon does not confirm whether models are free, their price, license, official status, affiliation, safety or fitness. Check the current terms at the source.

«Radiation 3D Models: Signs, Shields and Props»

Warning signs, trefoil markers and coasters are flat, single-colour prints that usually fit a small bed and need no assembly. Sensor shields are the opposite: functional housings with stacked louvres, a mounting bracket and a cavity shaped around a particular sensor. Decorative extruder and motor covers sit between the two, as small parts that replace or clip over an existing piece. Props and scale models, such as old television sets or soldier figures, come as multi-part kits that need assembly and paint.

On the author's model page, check the size and scale first, then the number of parts and how they join. Look at whether the model needs supports, which material and settings the author lists, and any photos of real prints. For sensor shields, compare the inner cavity and the mounting to the sensor you have; for covers, check screw positions and clearance around moving parts.

If the results feel too broad, search by the object rather than the theme: trefoil symbol, hazard sign, Geiger counter, dosimeter, sensor shield, Stevenson screen. Related terms such as fallout, post-apocalyptic, restricted zone or laboratory equipment bring in props and instruments. Adding a printer model or a sensor name narrows the list to parts that match your hardware.

FAQ

Questions fréquentes

What do radiation sign models usually include?
Most are flat plates or plaques, sometimes with a stand, a keyring hole or a wall mount. The model page normally states the dimensions and whether the sign is a single piece or a base plus a face.
What should I check before printing a radiation shield for a weather sensor?
Compare the inner cavity and louvre spacing with the sensor you plan to use, and look at how the shield attaches to a pole or bracket. The author's page usually lists the sensor it was drawn around and the wall thickness.
How do I find more models like these?
Try object names instead of the theme: trefoil, hazard marker, Geiger counter, dosimeter, sensor shield, Stevenson screen. Post-apocalyptic, fallout or restricted zone work well for props and display pieces.
How do I match a decorative cover to my printer?
Check the model page for the printer model and the exact part it replaces, then measure the screw holes and the space around moving parts on your machine before printing.
