Bug proofing raised bed

So just under a year ago we put in a raised bed - very useful but also a bit like a salad bar for bugs and mini-beasts. We want to grow some carrots under there this year - last year we made a cover for it which was never fully satisfactory (not quite the right size, not fixed down) so we remade it now for enviromesh, poaching some spare parts from an old fruit cage. This will offer a little protection for the plants in there, and will keep bugs out and - most importantly - it is now the right size and fixed down. Fixed it down with pipe clips - by a happy coincidence the pipe we used is exactly the same size as 15mm copper for plumbing, so we can use these:

Like this:

So overall looks like:

Hopefully this will hold it in place - we have 6 clips down one long edge, which will also act as a hinge so the other side can be lifted to access the bed. Next addition will need to be a support...
