- Jul31180Pcs M3-Hex-Spacers-Screw-Nut-Standoffs for DIY Quadcopter Small Drone, Computer motherboard - HOBBYMATE
These are very light weight, snug fitting spacers. While they are great for use on drones, adding very little weight while giving decent durability, I am using them in my diy electronics projects. They are non conducting, so the work great as spacers between the circuit board and the metal case I install them in. Not to mention they come presorted in a small yet secure/sturdy compartment case. At $.89, you can't go wrong.
