Yes, it's from Lisa as well (as most of the things on this pic). This type is no longer produced, but a new one is available, however it's more expensive (don't know how much exacly).
"Only" because I think that is about 60% done. Painting and assembly still to do 
Few words of comment on it:
- Last 2-3 boxes on each side are too far from each other, meaning there is nearly no place for TD once it's rounded and fitted to me (I'm pretty slim), but even using it's full length it leaves little place for td,
- it's gray... so it needs to be painted and from what I've seen it's not easy to keep the paint on something that will be bent. I plan to keep it in it's 'round' position at all times to ensure minimum paint chipping.
- it's foam and solid, yeah. Hard to cut it right, but luckily not so much of it in visible places was required 
Keep us posted if you make any progress
And remember to measure 10 times before cutting.
