Thanks so much for the guide, but I"m just wondering if you did anything with those clips (part "B")? I bought a similar one with similar instructions, but instead of those clips I have different ones. I'll attach a copy of the instructions that I was given and the clips, but from the diagrams I have no idea how to attach them, can someone can give me some tips?
Instructions:
The clips (part "B")

Here's what it looks like atm, to be honest it does seem stable enough, but the sides does seem like it'll come lose if you press it down.
Also here's a link to the
seller on ebay for anyone in Australia who might be interested in one with the same bumper like texture rather than a smooth plastic. (Not sure how much international shipping is)
