Flexible material

[limburgmetaal 9]

I have made some labels to mark my milling tools (SK40) as per picture
The material i used is PLA by Ultimaker.
Initial it is flexile, but after a few month the arms break.
Who can recomend a better material?

Ultimaker TPU 95A at 100% infill density.

PETG is my go-to material for use in a workshop environment

Good compromise between cost-easy to print-performance

In my experience, Nylon, ABS and PETG all provide much better long term performance.

i tried this, but is not giving the result that i was looking for.

I would use PET for this. Indeed, PLA tends to get hard and brittle, and to creep-deform, losing its clamping force. PET can handle this much better. Also, PET won't deform so easily in summer, or when sitting behind the window in the sun, of when left in the car. PLA will deform in a car, even in a mild spring or autumn sun.

 

But I would recommend that you modify the design: cut off a piece of the bottom, so that it becomes one big flat plate, and you can print the whole arc flat on its side. This will print faster, cleaner, and much stronger, because the print-lines will follow the curve. If required, enlarge the height of the label-area upwards, if it needs to have a certain height, e.g. to fit Dymo labels.

 

PLA (left, cream) deforming and cracking after some time, PET stays in shape better:

 

Recommended concept for clamps and labels: flat bottom plate for a stronger clamp, you get the idea:

Hi Geert,
Thanks
But the "flat" bit on the bottom is the marking area and the hole concept of the print.
On this you can write that it is "a 9mm Drill" and store it.
If you need the drill you will have it right away and don't need to measure the tool anymore.
The two arms are a bit spring loaded to hold the "flat bit"

What I meant was this concept:

 

This has a flat bottom to print it easily. And the print-lines will follow the curve and be much stronger, instead of being perpendicular and weak due to poorer layer-adhesion.

 

Yes, the front plate (the label area) might be a bit rougher than if it was sitting on the glass, so it might require a quick sanding, or a quick chemical smoothing, depending on the marker you use for writing. But I think in general this would be much stronger and longer lasting.

Embed a small magnet? 

The arms would just be asked to hold it level.
