My previous attempts to attach photos to my project log have failed. This time, I will do it correctly.

I've been iterating on my design for the storage falsie while I wait for my bra to arrive. 
I'm 42, and I've never bought a bra before, how exciting!

Once the bra arrives, I'll be able to scale the utilititty properly and make adjustments to the wall thickness to ensure the proper flexibility.

The basic idea is that the "back" / dorsal surface of the storage tit will be printed in a soft TPU, letting the "access doors" flex freely inward.

The "front" / ventral / boobie portion will be printed in whatever works best. Probably TPU, but maybe PLA. The point is people can choose. I may even be able to fit it into a mould and add a silicone surface. 

One of the engineering lessons I am always re-learning (one of the mistakes I keep making) is to keep things as simple as possible during the prototype phase. For example... I needed parts of the breast to have more TPU so it would hold its form a little better. I could have extruded some simple ribs (just like a real boob). But alas, that is not my way. 

Damask. I should add structural support with intricate patterns of organically swirling lines. That's what prototypes need.

The inside of the Utilititty has structural reinforcement in a Damask design I more or less made myself. There may have been some tracing, but not like, digital tracing. I hand drew this! 

I love damask patterns, and I will not apologize. But it does mean that when I make small adjustments to my model, it takes minutes rather than seconds to update. So that's not optimal. It's sort of a lot of suffering. 

Oh yeah... iterating on my design. Today I added those three tabs that will connect the storage tit to the base. There's enough flex in the TPU base that I can attach the form, but hopefully there isn't SO much flex that it falls off.
