Nipple Measuring Tool

My wife is currently pregnant with our first, and she wants to buy the correct size phlange for a breast pump. There are commercially available tools available but they're pricey. This was my first attempt to properly use Shapr and practice making a tool from scratch. I completely understand this may not be suitable for all, so please remix, redo, whatever you desire to make this better.I hadn't been able to find anything with a brief search of a few forums so I did this to hopefully provide some help to others. :)I recommend printing in 2 colours, I made the lines and the numbers higher so they can be printed easily in a different colour. 0.2mm nozzle gets all the details, but if you're not fussed on that, the 0.4mm will work. I hope this is OK.
