Multimeter protection

I was tired of losing/or looking for the protective tips of my multimeter, so I made something to avoid this. suitable for mustool MDS8207 plugs, most likely it will fit others because the type of plugs is quite common to all models..for the protection of the tips, you have to "force" to put them on, this prevents them from falling out on their ownfor the plug caps, you have to use a small screwdriver to stretch the ring, and only TPU allows thismaybe other additions to come, or improvem
