Small functional set of small phillips head screws. They are fairly common sizes. 1 is the smallest, 7 is the largest. These are not steel, so they are nowhere near as robust as a steel screw, so if you try and use a drill on them don't expect any decent results.

That said, they are pretty solid and will work fine for some light work (i.e. 3d printed models that require screws.)

They are scalable but don't go too small unless you have the bees knees of printers.

As high as your printer will go.

Print as per the design, head on the build plate and spike at the top. No supports needed. I printed at 0.06 but it should remain functional even at higher resolutions.

I have full intentions to make all different sizes which will be uploaded in due course. Right now I'm thinking that the main use of these will be for 3d printed projects that require screws or smaller screws for circuit boards. I will design and upload these in time.
