Wide PC Adapter for VIVO Under Desk Mount

My PC case is at the upper limit of the width for the VIVO Mount-PC01 under desk mount, so I wanted to build something more sturdy. 

It has taken some prototyping, but what I ended up with has OEM-like fit, uses the existing M6 bolts, and feels impressively sturdy. 

The weak point will still be the layer lines, but by building it on an angle I've tried to minimize the cantilever effect. YMMV based on the height of your PC and where it makes contact.

It uses 4x M6-1.0 nuts and is sized for the Everbilt brand nuts at Home Depot (US). They are thicker than some reference designs I found online.

My build settings were 4 walls with 15% infill using PETG.
