If you wanna print it yourself, the model is here: https://www.printables.com/model/1348194-4n-threaded-flat-head-screws-and-nuts-10-32-equiva
Design to be a drop in replacement for 10-32 screws with a much, much higher pitch. These screws are extremely easy to print, is reliable enough that it can hold some weight.
If you wanna print this yourself, you need to make sure that the screw is sideways, so if it breaks it’s no on the layer lines.
Using them in my own prints which had metal screws and they are holding quiet well.
A properly fitted straight bladed screw driver will fit snugly in the slot along it’s entire length. This offers more than the ‘two points of contact’ that your poorly chosen screw driver does. Add a hollow ground blade, they get an amazingly powerful grip. Learn to fit a screw driver properly and you will seldom have a problem with a slotted screw. As toolmakers and high end gunsmiths know and you don’t.
Of course, if you have neither the skill or enough ambition to be bothered to ensure the tool fits the fasteners correctly, you probably should choose a more foolproof tool and fastener.
Do I look like a rocket surgeon
Surgery is not required. You only need to 5% smater than the tool you are using.
