It happens that the shade of lipstick Peggy uses is commercially available. It also happens that one of the gadgets Peggy uses from time to time is a knockout agent disguised as lipstick:
You see where this is going, right? My lovely and talented spouse saw that someone had 3d-printed a "102 Sweet Dreams" case and thought that would be a suitable accessory. I agreed and ordered a tube of the right lipstick so I could properly measure a case for it.
I ended up making the case out of a whole bunch of pieces. There are the upper and lower halves of the case, of course (printed open end up to save a lot of time and support material), but I decided to print the cap-like ends as separate pieces for a smoother appearance. Likewise, to get a maximally good appearance for the name plate, I printed that as a separate bit and attached it rather than having that imprinted into the side of the printed design.
So, works pretty well. The bottom is snug enough to hold the original lipstick without having to shove it in, and it comes out reasonably easy for replacement.
