These got me out of a bind when my tools wouldn't reach in to a tight space. Half an hour of printing and the problem was gone

Very good model, I was a bit worried the end of the filament might easily pop off the side of the roll given how close the diameter matches that of a full refill but this hasn't yet happened. My only complaint is that the clips to hold the filament end aren't substantial enough to do the job but having printed the hex version this isn't a problem for me

Light yet robust, this has survived a few weeks with my toddler and is still going strong. Yes a couple of surfaces would have benefitted from being supported but I can appreciate the simplicity and reliability of going support free
