Well, actually I tried several times to make one and they kept coming apart. The feet need to be better connected I think. They kept pulling off whenever I tried to get it off the print bed. I finally gave up on it. There were also some other issues in the print. I think some of it may have been caused by some stringiness on my printer. However the next thing I printed with the same filament came out just fine and no stringy at all. (Shrug)
This looks like a fun thing. I may fiddle with it and try it again.
