Door Blind Hold Down Bracket - Hot Nut & Thumb Screw Version

A door blind hold-down bracket is the small plastic clip that keeps the bottom rail of blinds fixed to the door so they don’t swing around when the door opens, closes, or gets a gust of air. It is a tiny holding bracket for the heavy bottom slat of the blind.

This is my advanced version, you can adjust the range of the retaining screw (aka pin) and you can retract the screw to make the bracket openable, so you can then have the brackets secured to the door fully and there is no rotation or breakage when you are trying to raise your blinds. The day has finally come :)

Advice: No support required, print using a structural profile, I suggest 100% infill. And use PETG or stronger.

Static Bracket side: 3.2mm diameter peg with a 3.5mm penetrating height into blind slat.
Dynamic Side Bracket: M3 bolt (ideally M3x16), with a M3x3x4.2 hot melt nut, and a regular M3 nut.

This is a carbon copy of the ones on my door but with mild changes to strengthen key areas, and of course the advanced thumb screw from my own design (and needs).

How it works:

• The bottom rail of the blind has a small hole or pin on each end.

• The hold-down bracket is screwed into the door or window frame.

• You press the bottom rail into the bracket so it “clicks” in place.

• This keeps the blinds steady, especially on French doors or patio doors.

• My model has the advantage of being openable, so there is no bracket rotation (loosens/damage) and breakages are reduced dramatically!

Other names you might see for the same thing:

• Blind hold-down clip

• Blind bottom rail bracket

• Door blind retainer

• Hold-down bracket for horizontal/venetian blinds
