3d printed, colour will vary, depends on whats in the printer at the time. Now made to be used in multiple widths, 1, 2, 3, 4 wide so giving print widths of 10mm-220mm*. Simply but up the ends in the required position, insert a suitable 8mm bolt and tighten until firm. we can provide handles and bolts for 1, 2. and 3 wide.
These are printed in hard pla, however, some of the popular rollers are available in silicone or resin if you require. please contact if your interested. 
*(we do not recommend exceeding 3 wide.)

The final picture is of the rollers used on 6mm foam board, rollers no.2 and 26 have been rolled over this low cost foam board supplied by underfloorheatingstore. So the answer is yes it can be used on foam board but I would use a thin layer of acrylic filler over the surface to get the finer detail of some of the rollers, as in the video.

I designed and printed these, they are exclusive to me. allow a couple of weeks because it may have to be printed especially for you. colours will vary. 

if you have a particular texture that I haven't done, get in touch, after the skulls (84&5) I'm pretty confidant I can make anything you can give me a picture of.
