I’m looking to start keeping hardware for prints that need additional parts to complete them. A Pi case that I printed needed screws that I don’t have on hand and needed to go searching for some.
It got me thinking to keep a container of stuff ready that would get used often, but I don’t really know what to keep on hand. What do you have readily available?
I use M4 button cap and M3 socket cap exclusively. This is so I only need one bit for everything. I find they tap in so well that heat inserts are pointless in nearly all cases. I do recommend you use an electric screwdriver or drill to install them though, at least the first time. In cad I use 3.8mm holes for M4 and 2.8mm holes for M3.
There is a strong case for using self tapping plastic screws though, I just haven’t tried it.
