First off all, the idea is really good. I would have never thought of the idea of installing the monitor on the front panel. Before
@jermz1 shared the design with me, I modeled and printed a mounting solution that installs on the monitor rest / frame. Three separate parts (overall print time 30h) that needed to be bolted together. It wasn't even good, it felt rickety.
These brackets on the other hand are small and clever. However, I had some issues with the center pieces.
1) There's a gap between the panel and the mount.
2) Printed in PLA, it's not very sturdy. I broke mine when I pulled on the monitor. Maybe PETG or ABS makes it strong enough, but I only have PLA here.
and 3) The screw heads scratch the monitor.
So I took the idea and iterated on it:
It's narrower, so it fits inside the pocket leaving no gap. I found it strong enough even printed in PLA with a infill of 20%. The screw sits inside a hole, so the head is covered. It also hugs the monitor more, there's zero play. This does mean that if your monitor doesn't have the same as depth as mine (32GP850, 25.6mm), it possibly won't fit. YMMV.
