Ender 3 v2 Phone Mount

I have an Ender 3 v2 and I didn't want to obstruct the tool drawer or rely on the bottom left groove only, so I remixed darkpoet's excellent design to utilize the left corner.

Also I maintained the angle of the holder, but I made the piece flat so it doesn't need supports anymore.

I used M3x10mm bolts with printed t-nuts (link: https://www.thingiverse.com/thing:3050607), however M4s will work as well, they will just be a little snug.
