After around 12 hours and everything is cooled down, I manage to see the final result of my potting project. It seems like the pain has been well paid. The result is smooth as a delicious tofu. But after a very careful examination, I find a short crack. Not much, and definitely very tolerable.
Added: Duh, my mistake! I forgot to consider the top cover which has an elevated part a bit on the bottom side. So I think I need to melt the filler on the edge to compensate this… 🙁
I hardly push my ‘micro’ lens in order to capture this 4 mm crack. With another tweaking on Photoshop, I manage to get an ‘understandable’ figure of the crack.
