Dyson Vacuum Retainer (improved)

My vacuum was constantly coming apart when using it on rugs and carpet. I bought a replacement end cap once and it didn't fix it. The retainer is not well designed, and the original is too small/short to stay put. I modeled this in Fusion 360 and made the head of it slightly larger so that it 'snaps' as it should and doesn't come undone. I've used and tested this multiple times and it has functioned perfectly.

UPDATE: I just made some tweaks to the STL file because my printed part broke. I thickened the shaft and reduced the overall height slightly. This results in a MUCH tighter and secure fit. When you print, use lots of perimeters to strengthen it (I used 5 I believe).
