Holder with screw hole for Gardinia roller shutter mounting - design and 3D printing

📢 Listen (AI):

Hello my dears
Today I will describe one of my first projects completed with the help of a 3D printer ( Ender Creality Pro 3 ). This is the attachment piece for the roller shutter Gardinia , according to my own design. This roller blind as I found it is designed to be fixed "on the door" (no drilling, no screwing), so without my piece fixing it to the wall is problematic. I don't know if there are other/better blinds to mount, as I was put to the task of mounting this blind that someone had already bought. The piece I designed fits well with the mounting of this blind and has a suitable screw hole.
The design came about entirely out of practical need, I was helping someone install this roller shutter and this was my solution. Finally, I will post the CAD files of the developed model, so anyone interested can benefit.

Design of 3D model
I started by modelling the object that would be attached to my element. I had no intention of printing it. I intended to use it to fit my fixture to existing parts (i.e. as a reference):

I then prepared an already targeted element around it. The screenshot shows both elements and their matching:

And this is how the final designed element looked like:

And this is the element I have already printed.

Printing the part on 3D printer
I decided to print the project in Standard Quality mode. The print time was estimated at 39 minutes and the weight at 5 grams.

NOTE: To print an item without the so-called supports (supports) you need to rotate it 90 degrees from how it is shown in the screenshot above. I printed it this way and that way, compared both options and decided that it was better to rotate it and print without supports , than to leave it as it is and print with supports .

It came out reasonably well, although I found that the size of the mounting tabs (the two sticking out slightly) was a bit too big and I had to file them down slightly with a file. Nonetheless, the whole thing held together well as it went in tight.

Final fitting (the white piece from the blind inserted into my 3D printed black mount):

End fixation blinds
I'm not going to judge here the point of fixing the roller shutter where it was fixed. I did what I was asked to do. I just want to show how it was fixed.
I drilled two dowel holes in the wall and then tightened my fixings to it with screws.
Left mount:

Right mount:

Then I have already placed the roller blind in them. The whole thing holds solidly and does its job well:

Additional - leaflet of the roller blind used
For those who are interested, I am posting pictures of the leaflet of the roller shutter for which my bracket was designed. It shows how this roller blind is normally mounted, for example on a door. This roller blind is thoughtfully designed so that it can normally be fixed without tools (even on the instructions there is a crossed out picture of a screwdriver and a screwdriver).

The original way of attaching the blind is quite ingenious, but in my case it didn't work and so I had to come up with something myself.

Summary
The roller blind is holding up solidly and does not promise to have any problems.
The weight and printing time of the component make its cost nearly zero and its usability high (fitting it does not interfere with the other parts of the blind and allows it to be moved to another location later).
Using a 3D printer means that the component can be alternately modified , e.g. if necessary, move the hole slightly upwards by several mm when you want to make adjustments to the mount.
In the future when I have white filament I may re-print this part, but I don't think that will necessarily be the case as so far none of the blind users have paid any attention to the colour of the mount.
I hope that my tiny design described here will motivate someone to take an interest in 3D printing and show that this new trend really can solve a lot of everyday problems.
I am posting the source files of my mount:

NOTE: After printing, check that the catch from the roller shutter holds well in my mount. It should go in tight.

FAQ

TL;DR: DIY 3D‑printed Gardinia roller blind wall bracket: 39‑minute print, ~5 g plastic; “The design came about entirely out of practical need.” [Elektroda, p.kaczmarek2, post #18231795]

Why it matters: This FAQ helps home tinkerers rapidly model, print, and mount a sturdy blind holder without buying proprietary hardware.

Quick Facts

- Print time: Approx. 39 minutes in Standard Quality on Ender 3 Pro; part mass ~5 g. [Elektroda, p.kaczmarek2, post #18231795]
- Orientation tip: Rotate the model 90° to eliminate supports and speed cleanup. [Elektroda, p.kaczmarek2, post #18231795]
- Strength note: Layers aligned with force improve durability; rotated, no‑support prints resist shear better. [Elektroda, grabo86, post #18232169]
- Workflow used: Export to STL, then slice to G‑code in Cura before printing. [Elektroda, p.kaczmarek2, post #18238653]
- Installation: Drill wall for two dowels and screw the printed mounts; result holds solidly. [Elektroda, p.kaczmarek2, post #18231795]

What is this bracket and who is it for?

It’s a custom 3D‑printed wall bracket that adapts a Gardinia roller blind meant for tool‑less door mounting. It’s for makers who need a clean wall‑mount solution when the stock clips don’t fit their site constraints. The design prioritizes quick print time and tight fit. [Elektroda, p.kaczmarek2, post #18231795]

How long does it take to print and how much filament will I use?

Expect about 39 minutes of print time in Standard Quality and roughly 5 g of material per bracket. That keeps the cost near zero on typical PLA. These numbers come from real prints done on an Ender 3 Pro. [Elektroda, p.kaczmarek2, post #18231795]

Should I print with supports or rotate the model?

Rotate the model 90° and print without supports. Tests of both approaches showed better results and less post‑processing when printed rotated. This also reduces waste and improves surface quality on the functional faces. [Elektroda, p.kaczmarek2, post #18231795]

How does layer orientation affect strength on this part?

Print so layer lines run perpendicular to the dominant load path. “The rotated version without support is a better solution in terms of durability,” because layer bonding resists shear more effectively that way. [Elektroda, grabo86, post #18232169]

Can I just screw the factory Gardinia bracket to the wall?

Avoid using the two rectangular factory holes for wall screws. They are latch slots, not screw bosses, and tightening screws risks cracking the plastic. The printed adapter adds a proper screw hole for reliable fastening. [Elektroda, p.kaczmarek2, post #18238653]

What printer and settings were used in the successful build?

The bracket was printed on an Ender Creality Ender 3 Pro using a Standard Quality profile. That profile delivered the 39‑minute, ~5 g result and good dimensional accuracy for a tight friction fit. [Elektroda, p.kaczmarek2, post #18231795]

What’s the exact workflow from CAD to print?

Basic flow: 1) Export your modeled part as STL. 2) Open STL in Cura and slice to G‑code. 3) Print the G‑code on your Ender 3 Pro. This path is proven for the bracket here. [Elektroda, p.kaczmarek2, post #18238653]

How do I mount the blind with this printed bracket?

1) Drill two wall holes and insert dowels. 2) Screw the printed mounts to the wall. 3) Press‑fit the Gardinia end pieces into the mounts and seat the roller. The assembly holds solidly in service. [Elektroda, p.kaczmarek2, post #18231795]

What if the catch is too tight or the tabs are slightly oversized?

Expect a tight press‑fit. If tabs are a hair large, lightly file them until the white blind insert seats flush. The designer noted this small tweak during first fit. Tight engagement prevents rattling during use. [Elektroda, p.kaczmarek2, post #18231795]

How can I fine‑tune bracket height after drilling?

Print a revised bracket with the screw hole shifted by a few millimeters. Swap the part and reuse the wall holes. This rapid iterate‑and‑fit loop is a key advantage of 3D printing. [Elektroda, p.kaczmarek2, post #18238653]

Is Blender OK for modeling parts for 3D printing?

One view is that Blender isn’t ideal for dimensioned mechanical parts; simple assemblies and precise sizing can be cumbersome. Quote: “Actually, it is not suitable.” Consider CAD‑oriented tools if you need parametric control. [Elektroda, .:KoSik:., post #18240657]

How do I generate G‑code for the Ender 3 Pro from my model?

Export the part to STL, open it in Cura, and slice to G‑code using your chosen profile. Then print from the generated file. This was the exact method used for the featured bracket. [Elektroda, p.kaczmarek2, post #18238653]

Where can I get the source and STL files?

The author shared both original CAD sources and an STL attachment with the post. Download, inspect dimensions, and test the tight catch fit before installation. [Elektroda, p.kaczmarek2, post #18231795]

Any tips on color and aesthetics?

White might match typical blinds, but the black prototype has drawn no complaints. Reprint in another filament color later if desired. Function and fit remain the priority for this mount. [Elektroda, p.kaczmarek2, post #18231795]

What failure modes should I watch for during installation?

Do not drive screws through the factory rectangular slots; they can crack. Ensure the printed hole carries the load, and verify a snug catch. Lightly deburr or file high spots to avoid stress risers. [Elektroda, p.kaczmarek2, post #18238653]
