While you've well done what you set out to do, and replacing the bit of trim when you need to will be trivial, I note you could have left the trim in place and fit the desk there a couple different ways. You could have simply elevated the desk with bespoke feet the 2 1/2" (or whatever the trim height it), or notched and slightly bent the metal leg on that side of the desk. As I've done a lot of interior finish, I've faced similar problems in the past, and would be happy to provide such insight as I may should you seek it in the future.
Anyway, you've done what was needed, and that's what matters.
Merry Christmas!
She's only 5 and the desk is already a bit tall for her, so raising it up another 3-4 inches is out, but I'm not against refabricating that metal foot on the one side. In this case I just picked the path of least resistance. While many of my resources are limited right now, the one I seem to consistently lack the most of is time, and this gave me one satisfactory result with the least amount of time involved. My plan over the next few years is to be in a position where both my time and income allow a more leisurely lifestyle where I can take my time with something like this. Who knows, I might even start doing things for fun again and farm some of this work out. For now though I've got a massive amount of work to do. Anyway, thanks for the comment @valued-customer and Merry Christmas to you too!
I am fortunate in my work, as it's what I want to do for fun =)
