RepRack hook-and-loop strap label tags

My earlier design for a RepRack Hanger Lock secures the RepRack hanger and rails to the RepRack wall cleat.  This prevents the hangers and rails from popping loose by minor bumps and shakes.  That's all well and good, but the filament spools need to be secured to the rails.

The solution: Hook and loop straps (aka Velcro) around the spool and the rails. I tried a few different velcro solutions, and here is what worked for me:

1. My favorite: 18" x 1" cinch straps.  I was able to get these online in packs of 25 for about $20.  I like the cinch strap mechanism--it lets me get the strap nice and tight. Sadly 18" is not long enough for most filament spools, so I need to connect two of them per spool.  This still is my favorite of the bunch.
2. Cut to length self-gripping Velcro.  I was able to find a 45 ft 3/4 inch roll for about $16.  I cut it into 3-ft sections.  This works, although I do kind of miss the buckle that the cinch straps have.
3. 24" x 1.5" cinch straps.  I was able to find these online in packs of 12 for about $16.  These don't fit around a full filament spool, but they work well on partially used spools.

If you find a cheaper or better type of strap, please let us know in the comments!

I've also created some simple filament label tags for you to use on your straps. These tags can be threaded onto the Velcro to identify which roll is which. They are two-color friendly--a filament change at the right layer will make the text stand out!  I've made tags for most common filament types, and there's even a blank tag that you can write on with a sharpie, or you can use the "add text" feature available in PrusaSlicer 2.6 and above.

I've included the original OpenSCAD source file as well.

I printed in PETG but I suspect PLA will work just fine as well.

Please let me know if you found this info and the tags useful.  Thanks for reading!
