M4 nut cap (plain for remixing)

I needed a basic m4 nut cap to glue stuff to and couldn't find one so just took this one and made the outside featureless. Shaved mine down with an x-acto knife to fit for my purposes so don't have a photo of how it looks off the print bed. Posting in case this is useful for anyone's projects. NOT a friction fit, will need to be glued if you want it to stay on.
