OpenSCAD – Busy Ducks / Making You Pro'duck'tive Mon, 20 Apr 2020 10:52:06 +0000 en-US hourly 1 https://wordpress.org/?v=5.8.3 /wp-content/uploads/2015/07/cropped-favicon-55963284v1_site_icon-32x32.png OpenSCAD – Busy Ducks / 32 32 Parametric VESA Mount Fixer. /parametric-vesa-mount-fixer/ Mon, 20 Apr 2020 10:52:06 +0000 http://busyducks.com/wp_4_1/?p=1006 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”.

  • VESA Mount Fixer (configurable)

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:

FeatureVESA
Middle		VESA
Bottom
Monitors line up nicely when sharing a mount. YesNo
Monitor is stable and does not roll violently on mount.YesNo
Monitor can be used in portrait mode without a rigid mount.YesNo
Monitor won’t drop forward overtime on an adjustable mount.YesNo
Mounting high on shop wall hides what is behind screen.NoYes
Monitor is cheaper to produce.NoYes

The result for a shared mount was quite noticeable.

  • Before
  • After

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

How it works.

Customisation

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

CAD View.

The following parameters should be altered to suit your need.

ParameterValuesNotes
correctionThe distance to move the screen down.
washer_sizeCreates 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.
