I got this replacement head band from aliexpress and the first thing that failed was the slider. I figured, why not repair it? As with my other designs, I try to make it functional but beautiful.
STEP and Fusion project files are included. You can change it any way you want. Yes, one side is slightly shorter. That's to make it bend naturally!
Make
I printed on Prusa Mini with 0.25mm nozzle and 0.07mm layer height, 100% infill with Devil Design PLA.
Parts and supplies needed
For one side:
3x M1.7 self tapping 3mm countersunk screw with flat bottom. Like the ones found in plastic housings.

2x printed parts. You need outside and inside.
Both parts are in one file, some slicers ask if it is one object of multiple parts. Press no)
How to
print parts
put first screw in inside part
press outside against headband
put the headband and inside part together with the outside part
screw in the first screw but don't fully tighten (this is a little hard sometimes)
screw in the other screws, again don't fully tighten
slowly and carefully tighten the screws, don't overdo it because you will strip out the plastic
adjust to your liking, tighter means harder to change headband position.
