Side-shift Bracket for Door-mounted Venetian Blind

Problem

A door-mounted Venetian blind is just wide enough to cover the glass pane, yet when the door opens (inwards), the blind would strike the sidewall of the door aperture.

Solution

The blind is mounted on special brackets with a slider mechanism.
As the door opens, a pushrod displaces the blind sideways away from the hinge, hence clearing the wall when the door is fully open.

Hardware

• Blind :  50mm slat-width wooden venetian from MakeMyBlinds:

Printing

• SLIDEBRKT      Qty 1 PAIR  (mirror the LH model in your slicer to make a RH)

I recommend the print orientations shown in the photos.

Finish

I primed and spray-painted the FDM items in order to minimise dirt and discolouration.

A dry graphite lubricant helps the sliders to operate more freely. Even pencil lead dust can be used, though beware of it marking the visible surfaces.

The back face of the blind's casing needs to be drilled with 4 x Ø8 holes that will accept the pegs of the slider mechanism. Before drilling these, carefully lay out the mechanisms and determine their lengthwise position, so that the start and end of travel are where you require.

Also, the uppermost slat of the venetian blind can be trimmed in order to clear the special brackets. See images.

FreeCAD source model included

FreeCAD users might be able to remix for other brands of venetian blind.

The shift travel (stroke) could also be increased by changing the small pivot bracket, to stand the pivot further off the doorframe. Correspondingly longer dowel rods might be required.
