About this 3D model

This was made to fit an old Eureka canister vacuum, model 3334. I used pop-rivets to attach it, and the pressure from the rivets broke the plastic, so it might be a good idea to use machine screws and nuts? The fit is not perfect, but it worked. The gap could be made a half mm smaller, and the bussiness end could be made to reach in another mm or so. If I have to repriint it, then I will make it better. Hope that helps.
