Printed some of the other great designs on here, but wanted some for a few friends who were feeling down.
I used Suraky's Surgical Strap https://www.thingiverse.com/thing:4249113 as a base (thanks)
Then somehow created the 3d letters and fitted them in - ( I googled it and took a punt)
tbh it was a bit of a bodge job as I really didn't know wtf I was doing then, (I'm a little better now, but still a rank novice) but a) it worked, and b) I made someone who was a little depressed happy
Totally forgot to take a photo before I sent it off - so you will have to trust me that it worked
I've been working on some others I will upload at some point - mostly super hero logos just printed for friends and family, but we did run a few off in exchange for donations which we gave in full to Hearing Dogs for the Deaf (well Ear savers, Hearing dogs, it kinda made sense :-) )
