I like the original hook as it was easy to print and the design was simple. However the original hook didn't fit our cubicles and after many revisions and suggestions from co-workers ended up with this design. The edges have been rounded, cut out some filament in the middle and it's wider so it fits tighter and slips off less. Enjoy!
