I was searching for an easy to print, multi-purpose strap that could be printed in TPU (Ninjaflex) for cable management and other organizational tasks.
I found this file:

and the recent remix, but they both had errors. Multiple un-joined bodies, non-manifold faces, my slicer wasn't happy with it, and neither was I.
So I used meshlab and then FreeCAD too make this version.
I lengthened the nub, added a chamfer on the underside, and extended the strap as one piece. The result is a very firm holding strap that printed beautifully.
