Gridfinity Bin Labels Hexagon socket head cap screws ISO 4762 former DIN 912 M2.5, M3, M4, M5, M6, M8, M10, M12, M14, M16, M18, M20

The labels are for these gridfinity boxes: https://www.printables.com/model/592545-gridfinity-bin-with-printable-label-by-pred-parame

The bolts are to scale as far as possible. When the screws get too long for the label, the bolt figure is broken.

Print it at 0.2 mm layer height and make a filament change in layer 3.

I was asked multiple times how i generated these, so here is a short How-To using Fusion360:

You need two steps: 

1. Parametrize your model
2. Write a Script that loops through all your variants, saves them by a usefull name and zips them on its own. Additionally take a screenshot for a nice .gif.

1.) The tricky part is the parametric text, as Fusion does not (yet) support this. There is a “ParametricText” App in the Appstore, however this does NOT work with scripts. Go to the GitHub page and get the ext-trigger fork.
Once you got this installed by placing it inside "%appdata%\Autodesk\Autodesk Fusion 360\API\AddIns" you can use it in Autodesk. See the Appstore page for help.

Hint: After saving and loading, sometimes the app messes up and the format of the text is all over the place. Simply assign the sketch/text again to your parametric setup if you have trouble.

2.) in Fusion360, under Utilities/ADD-INS/Scripts and Add-Ins you can create yourself a python script that basically controlls Fusion360. 

It will open Visual Studio where you can create your script. You can take a look at mine and take it as a starting point. I am not programmer nor is this by any stretch an ideal script, but it works. The script below looks terrible here on printables, copy&paste it into Visual Studio for propper formatting and highlighting. I added some comments, I think it is easy to adapt. Use ChatGPT for help if necessary ;)

Once you got it set up you can lean back and watch your script run. Fusion runs quiet slow, my script took a couple hours for all variants, so better start with a small batch to make sure everything works fine.

These labels are for the bins made by @Pred_457770 and are based on his original great design. I just expanded the available dimensions for a box that is 1 grid whide or 2 grids whide.

The M3 labels are uploaded as single files.

For M3 and all the other diameters i uploaded all length from 4 mm to 200 mm in zip-archives.

Edit 12.03.2024: Added M2.5 as suggested by @MrREH_1050391

Edit 09.10.2024: Added the Fusion360 files. They are not really well prepared/labeld but were requested. For the ParametricText plugin to work, upon opening the file, re-assign the text in “Skizze3" to the parameters. Otherwise this will throw errors.

Edit 13.11.2024: Added M2.5 length in 2 mm steps, was missing before.
