This is an openscad model, which you can edit with the “Customize” button.

It's my first openscad script, so it's quite simple, but does the job.

Options:

• Width, Depth, Heigth, HoleWallWidth
• font size, style, height
• hole on the left / on the left and right
• 1, 2 or 3 lines of text

The one in the picture is 55x16x2mm, HoleWallWidth 4mm, FontHeight 1.5mm

If you like you can print in two colors, just change at the right layer.

I'm using them with carabiners eg amazon.de (affiliate link).

As of today (May 2024) makerworld only supports "Arial" in the online editor.

So changing the font has no effect.
