Stihl Magnum Blower Nozzle Strap

I made this thing to replace the worn out velcro strap that came with my Stihl Magnum blower. I designed it for nylon; YMMV with other materials. It secures to the nozzle with a small ziptie, and hooks to the top corner of the blower (as shown in the photo), to keep the nozzle at bay during storage and transportation. The Stihl nozzle measures 42mm diameter where the strap goes. I added 3mm radius to give a looser fit for easier operation (and so it dangles out of the way while using the blower). The strap is 2mm thick, and the hook part is 4mm thick. So it won't burn a ton of filament, nor will it weigh you down.

Appropriately, this was my first print using some 0.17mm nylon weed trimmer line I bought on clearance sale at the local hardware store. My enclosed A8+e3d did a great job at 0.2x0.45mm, 260/100C (45C ambient), and 40mm/s. The resulting strap (and the part on the blower where it hooks to) easily supported the weight of the motor when I held it by the nozzle and shook it around. It also doesn't unhook while carrying the blower by the handle (a pet peev with the stock velcro strap).

Enjoy, and please share if you find it useful for your blower, or something else.

[update: Unfortunately, after a decade of good service, my BR600 spun a bearing and scored it's cylinder after running it for a few minutes with a carb problem. The repairs would have cost more than the BR850 I bought to replace it. It was a wonderful tool while it lasted. I have to say, I've never seen a motor run so well with poor mixture like that... it is very different than your usual 2 stroke that will bog down a ton accelerating while lean. It got the job done and felt almost like it does normally... just slightly slower throttle spool up was all, but still ran at the same max rpm etc. So beware 4-mix owners... if it even has a short hiccup, you should play it safe, stop working, and check things over to be sure you don't have a lean mixture condition (maybe even keep a temp sensor on it to be sure).]

Notes:

Print in nylon with 0.2mm layers, 5 line brim, and all 0.45mm walls. By all walls I mean sliced with a 'too high' wall count. 100% concentric infill may work just as well? My 4mm borosilicate bed with pva glue stick yielded a '0 deformation' part.
