Brass standoffs are essential components in electronic projects, particularly in applications where circuit boards need to be securely mounted within an enclosure or chassis.
Here's how they are typically used:
Board Mounting: Brass standoffs are used to elevate and secure printed circuit boards (PCBs) within an electronic enclosure or chassis. They provide a stable platform for the PCB, preventing it from coming into contact with conductive surfaces that could cause short circuits.
Mechanical Support: Standoffs act as spacers between the PCB and the mounting surface, ensuring proper ventilation and preventing heat buildup. This is crucial for maintaining the integrity of sensitive electronic components.
Isolation: Brass standoffs help to electrically isolate the PCB from the chassis or enclosure. This isolation is essential for preventing electrical interference, reducing the risk of noise and signal degradation, and enhancing overall circuit performance.
Easy Access: Standoffs facilitate easy access to the PCB for maintenance, repairs, or upgrades. By raising the board above the mounting surface, technicians can easily reach components and make necessary adjustments without disassembling the entire system.
Vibration Dampening: In applications where vibration is a concern, brass standoffs can help dampen vibrations transmitted to the PCB, thereby reducing the risk of component failure or solder joint fatigue over time.
Grounding: Depending on the design, brass standoffs can also be used as grounding points for the PCB. By connecting the standoffs to the ground plane on the PCB, they provide a convenient and reliable grounding solution.
Overall, brass standoffs play a crucial role in ensuring the structural integrity, electrical isolation, and proper functioning of electronic systems. Their versatility and reliability make them indispensable components in a wide range of electronic projects.

Want to build your own weather station? This sensor kit has a cup anemometer and wind vane to measure wind speed and direction and a tipping bucket style rain gauge, together with associated mounting hardware.
The sensors in this kit are active mechanical sensors that work by physically interacting with the wind and rain. They use magnets, reed switches and moving parts to produce simple signals that a microcontroller or single board computer can use to calculate wind speed, wind direction and rainfall.
The sensor cables are terminated in RJ11 connectors (each sensor only uses two wires though, so if you wanted you could snip off the ends and connect the wires to a different kind of connector). Armatures to mount the sensors are included, as well as a short metal mast that can be lashed to the top of a suitable pole with the included jubilee connectors.
Please note that this kit contains the mechanical wind and rain sensors only, and doesn't include any microprocessor electronic components. You'll likely want to hook these sensors up to something like a Weather HAT (for Raspberry Pi), a weather:bit (for micro:bit) or a Weather Shield (for Arduino).
What's in the box?
1 x Wind vane
1 x Anemometer
1 x Rain gauge
1 x Sender housing
1 x Short metal mast (made of two metal poles that slot together)
2 x plastic arms for mounting the sensors
Mounting hardware: jubilee clips, nuts, bolts and cable ties

Here is a video from CNC Kitchen, he teaches how to install embedment nuts into 3D-printed parts.
3D printing plastics often have low yield strength and cannot reliably produce threaded features. Embedded metal nuts provide stronger and more precise threading for hidden fasteners. The nut melts and reflows the plastic around it, enhancing its strength. However, there are design constraints - the nut must be on a part face and cannot be reinforced beyond the plastic's properties.
