Simple screwdriver stand for wall mounting - design and 3D printing

Hello my dears
Today I'm going to describe here my screwdriver organiser/stand/segregator that mounts on the wall.
I designed the whole thing first in the 3D modelling program Blender, and then printed it on a 3D Creality Ender Pro 3 using PLA filament.

Project ideas
The idea of such an organiser for screwdrivers is quite old and I myself have encountered it already in a wooden version, i.e. it was simply a board screwed to the wall and holes were made in it. But progress is moving forward, so I thought, why not print something like this for myself on a 3D printer? I decided to give it a try and gave myself the following assumptions:
- the model should be simple, without unnecessary additions
- model will be printed in ' Low Quality ' mode, that is the fastest one
- the model will have 10 screwdriver holes and two fixing holes
- the model will be made in Blender and will be made parametrically in Blender (i.e. I will be able to quickly change the number of holes and their size at any time, without having to edit each of the holes individually)

Element design
I started by designing the element in 2D. I assumed a hole spacing of 20 mm and a hole size of 5 mm .
The whole piece had dimensions 10 mm on 180 mm .

I also took the liberty of printing out a test piece, just for a live fitting. Specially one that is flat so as not to waste the filament. This sort of thing avoids any major/trivial errors getting into the final model.

After printing the above model (it only took 15 minutes to print!), I made the first fittings to my screwdrivers:


It came out pretty well, so I didn't actually make any big adjustments, just slightly resized the holes and started to develop the design. I added fixings, made it thicker, and extended the holes to make the screwdrivers hold solidly.
The final version of the piece looks as follows:

Additionally, I give a screenshot of the dimensions shown:


Print of the component
I imported the final model into Cura and started printing.

During the printing process, I observed that the 3D printer first applies a sort of border to the model (and the holes) and then only fills it in. Image is the photo below:


After less than two hours (according to the time estimate from Cura) the piece was ready. It came out like this:

It looks promising, but will it work? We are about to find out.

Final result Final result
In the end, I prepared the following kit for myself to assemble (printed piece-organiser, two screws, and screwdrivers):

I mounted the whole thing on a wooden wall in the workshop:



This is how the organiser already looks in use, along with a set of my torx screwdrivers (and a few others).


Summary, conclusions
I am very happy with the design. It is small, simple, and yet pleasing. As for improvements, I guess the only thing that could be done would be to extend those bushings of holes to make the screwdrivers hold more solidly in it, or make a version with two rows of holes.
The length of each piece is unlikely to be able to exceed 200mm in my case, as I am limited by the print area of my 3D printer ( Ender Creality Pro 3 ). Theoretically I could try after making the model to rotate it and align it diagonally, but I think the game is not worth the candle.
The organiser will certainly last me a long time, and even if by some miracle it gets damaged (which I doubt, the print is very solid and hard) I will just print it again.
