Parametric VESA Mount Fixer.

Recently I encountered a monitor that used a different mount positioning despite being only a few digits of in model number to its neighbour. The monitor needed to live with the other, sharing a horizontal mounting arm. I created an OpenSCAD mount to convert “lower mounted VESA”, to “central mounted VESA”.

Background

Some manufactures put the VESA mount at the bottom of the screen, others in the middle. This can cause an issue for many situations, especially if monitors need to be used on a shared mount or in portrait mode.

Lets compare the pro’s cons of the mounting styles:

Feature	VESA Middle	VESA Bottom
Monitors line up nicely when sharing a mount.	Yes	No
Monitor is stable and does not roll violently on mount.	Yes	No
Monitor can be used in portrait mode without a rigid mount.	Yes	No
Monitor won’t drop forward overtime on an adjustable mount.	Yes	No
Mounting high on shop wall hides what is behind screen.	No	Yes
Monitor is cheaper to produce.	No	Yes

The result for a shared mount was quite noticeable.

The plate which pokes out, should connect to the monitor. The other to the VESA mount (See below).

Customisation

The mount can be customised in OpenSCAD, or via the Thingverse customiser: https://www.thingiverse.com/apps/customizer/run?thing_id=4300602.

The following parameters should be altered to suit your need.

Parameter	Values	Notes
correction		The distance to move the screen down.
washer_size		Creates pockets for washers and bolts to sit flush in. Use zero to disable.
connection_size	>=30 and <=100	The size by which the central column extends over the top of the VESA plate. Significant trade of between material use and strength. 30 produces a cheap print and holds light monitors. But 80 should be used for heavy displayed, or displays someone may pull downward on.
step	>=0 and <40ish	Total recess size (depth) of the adapter.
thickness	> 1 and <=step	Thickness of the VESA plate. This must be >= the depth of any pocket the vesa mount will sit in. Probably don’t go below 5 if 3D printing.
