Which Puma do you mean? The German or the Israeli?

The IDF one isn't an IFV but rather a CEV and has no turret.

It`s no anti-skid surface, it`s an anti-bomblet "armor". These are actually mats with rubber hairs to bounce of bomblets.

Lower right corner of image: Rubber "spikes" as bomblet protection.
Lower left edge of image: Top of ladder with two strips of anti-slip coating.
Top edge of image: "Green" armour modules with some smooth surfaces and a rectangle of rough surface on the top. Black strip between hatch and the armour modules is also covered with some coarse material.
Note that there are small smooth surfaces as well.
Also visible are the rows of small holes in the bar armour strips ...






Note difference between coarse and smooth surfaces ...
Good side view of the rubber "spikes"

The rubber spikes are the same as those seen on the PzH 2000 :

For those who dare building it detailed:
3,5 mm in diameter and 35 mm long.

0.1 mm x 1 mm
getting wire is easy
drilling 0.15 mm holes is not easy, especially LOTS of them. The section in Frenchys image has approximately 500 of them ....
Maybe if the holes could be etched and then insert the wire in pairs as U's from behind.
The pegs seem to be 12.8 mm apart, center-to-center, which comes to 0.37 mm

Many of the suggestions in the "3D Suggestions" thread are ridiculously easy scratch building projects. These mats however would be perfect for 3D printing.

Even if the can be printed, I wonder if they would survive package and transport?

Whoa! What is this? The new zimmerit?

A worthy modeling challenge! Can it be done? Is it to be avoided?

I did little tiny wires on a 1/72 Sherman to represent the welded on nails seen on some Pacific Shermans. Oversized for 1/72 of course but it just did not seem right without them. This needs a more 'industrial' solution to replicate. It seems a flexible mat cut to size would work best....

Nick,
this is an anti-bomblet armor against airburst attacks. The hairs are flexible and should bounce of bomblet munitions. Not sure if it works and the mats needs to be replaced since the "hairs" will break after some time when crews walk over it. At least you don`t have to worry about camo painting. The mats remain in their rubber black color.

A couple of years ago I claimed I was going to find a way. I took a piece of PE (from some HO scale stuff I had from way back) with tiny holes in it, and smeared silicone caulk over it. It worked, sort of. First off, the holes weren't deep enough, and since I used clear silicon (all I had lying around) it looked a little odd.

I lost interest and never reported my findings. Besides, my PzH 2000 was already built.

If I had it to do over again I'd simply stack three of the PE pieces on top of one another, touch some solder to them, and the holes would be deep enough. I believe there is a black silicone gasket material that will look right. I promise you all this works. Whether it works with three pieces stacked remains to be seen. From what I've been reading a lot you have LOTS of time on your hands right now.

Lots and lots of tiny pegs supporting each other would probably be easier to package safely than other parts.
I think it would behave as a flat part with surface structure.

I agree with you. I build me an HEMTT A4 engine compartment instead of spending 90 bucks on a part from Shapeways.
