New cranks for my wife means yet another spiderless chainring standard, and in the case of SRAM 8 bolt chainrings, this means 8 tiny proprietary M4x8 screws to not lose.
I thought about putting them in a little ziploc bag and zip tying that to the chainring, but I have printers and every problem has a printable solution, so here we are.
Simple part, quick and easy print. Suggested 0.2mm layer height, 2 shells, infill can be the default. This doesn't need any strength.
Although the screws usually go in from the back of the chainring, putting them on the front keeps the overall size smaller, but obviously how you install it is up to you. Threads are not the full depth, just a little bit at the end so you don't spend all day threading them in. Just enough to hold securely.
Just remember that these M4 threads are small and don't have a bunch of engagement so don't tighten them down past snug or they'll probably strip out.
