Hearing Aid Earbud Cap

I designed this from a hearing aid mesh I found. It took me quite a while as i'm new to this. It would be best printed from a flexible filament, and the whole can be changed using fusion360 and the like. You can adjust the scale to fit snug. Dont use support. The hole can be adjusted via file depending on level on expertise. The earbud should fit tightly with the headphone, to amplify sound and prevent background noise. I found the looser the fit, the better range of motion with the headphone being able to turn n a swivel point. If it serves you well plesse tip me :)
