I thought about this one a while ago and it's kind of 6 of one and half-a-dozen of the other.... Sure a spring loaded roller assy. uses less belt, but it's likely to be a lot more bulky potentially in a spot where "a lot more bulky" may not be cool. You can buy ready made spring roller blind units made for machine guarding, but for narrow widths all the ones I've seen are a bit cumbersome, whereas running it back through the extrusion the bulk of the belt is all stored in what otherwise would be dead space.

On another subject Zeeflyboy. what kind of % power do you find is best for laser "engraving" stuff on your anodised bits please?
