After yesterday’s pathetic attempt I decided to start with the metallic elements first to get a sense of how much headroom I will need to get everything in place. This led to a much better result. While making those internal plugs in all their details isn’t really that important, they help going through the design process. I’m pretty happy with the layout, the external rubber cap is nice and flush with the rest.
I like those “industrial looking” surface notches, normally you use these with a sort of socket wrench to tighten some fittings. As with the rest of my leather objects, the back of the leather panel will receive some generous padding to get rid of most of the gaps.
