Laptop behind monitor mount

• for use with a VESA pattern monitor
• in my case I needed to mount my laptop behind a monitor with the laptop's screen exposed as an addition monitor
• the monitor was an HP L2245WG (22", I think) which had its own stock monitor stand I needed to work around
• I don't think I have any pictures of it in real life, but it worked fine in PLA & was plenty strong - similar pictured attached
• uses M4 hardware to piggyback to the monitor, M4 x 30 mm IIRC
• adjustable arms compensate for thicker or thinner laptops (I used it with a Dell Precision 7540, which is fairly thick)
• I used a piece of cardboard to avoid marking up the trackpad & triggering the keyboard
• vertical adjustment features to allow laptop screen to be positioned wherever you like relative to the center of the VESA mount - logically so that the bezel of both screens line up
• I was going to improve the design & CAD, but gave up because I have better things to do now

2024-01-28 rev 7 assembly instructions

Here is a view of the assembly, only one side:

• I was too lazy to mirror the components
• note that I'm pretty sure I never tested, let alone printed rev 7 parts
• when you print the parts, you'll have to mirror 2 of the 3 unique parts, the HOOK & the ARM

All the hardware is M4:

• I put down qty 3 nylock nuts
  • qty 2 for adjusting the HOOK in its slot relative to the ARM in order to accommodate laptops of different thickness
    • I used a piece of cardboard on the keyboard side to mitigate damage to the keys
    • 
  • qty 1 to lock the ARM vertical adjustment relative to the MOUNT
    • 
    • the idea behind rev 7 was to reduce the fastener count on this joint by leveraging the edge which already existed as a sort of sliding rabbet joint

MOUNT

• The mount has a square hole pattern for a VESA 100 x 100 mm mount, also using M4 hardware IIRC
  • the corner holes are reserved for that purpose
  • the holes in the vertical row are for fine tuning the adjustment of the ARM up & down to position the laptop screen wherever you'd like within reason

• The reason why it's a U shape is because my monitor at the time was some HP L224G monitor or something & I wanted this stand to work with the existing desk stand that came with the monitor
• Therefore, I needed this U shape to reach around that stand to utilize both simultaneously
• If you had a generic VESA stand, this part might still work
