A case to hold the short tips for the Pinecil V2 soldering iron

I wanted a compact way so store and protect the extra tips I bough for my Pinecil V2 but I couldn't find anything good online so I designed one. If there is interest I could upload a stretched model that will fit the longer tips as well. I don't have any so someone would have to let me know how much longer it needs to be. I am also planning on designing an outer sleeve for it.
