## Description

Review: Order this and you won't get screwed. <-- see what I did there? - One of my new hobbies is 3D printing and the hardware to hold enclosures together can be either self-tapping screws or regular screws and brass inserts. I like to use the latter as I can open and close the box as much as I like without the holes rounding out. This set is a collection of assorted M3 length cap screws, nuts and an allen wrench. All good quality and plenty of each length. Next time I may just buy a specific length, but having an assortment is a great way for a beginner to start out.
Review: Great kit for 3D printing!! - Great assortment M3 screws and nuts! This hardware comes in very handy for some of the items that I have 3D printed. Pros- Various length screws in this kit make it very versatile. Nice to have what you need on hand, and this kit fills some of that void. Cons- None that I have run into so far, and I have used them on several projects.
