Great to see that it is nothing worse than replacement parts as it could have been so much worse.

I generally after assembling anything that involves precise alignment, vibration or heat cycling re-torque the bolts after a week of use as it is not unusual for them to need retightening. Likewise, I check tyre pressures regularly & also increase pressures if I know I will be carrying heavy loads. I know somebody that survived an underinflated disintegrating front tyre at 70mph on a motorway & they described it as being a passenger of fate as they had no control over the outcome, but they fortunately got away with it.
I was discussing safely earlier on Twitter, where as a 16yo, the first week of my electronics apprenticeship at RAE Farnborough was all safety lectures & films about keeping yourself safe & also those around you. Having this dinned it at a young age has made me always instinctively & often unconsciously think about safety as part of planning anything. Using a bench grinder, when sharpening tools, drills etc was an immediate sacking offence if you were caught not wearing safety glasses, where you had your own pair & there was always a pair also hanging from the grinder. The habit still survives as my garage bench grinder always has a pair hung on them, which being next to my pillar drill I always use them with that as well.
A good tip is that if you are working with anything sharp keep you hands behind the sharp end. I can't use kitchen knives without a chopping board, so my hands & fingers are always behind the blade,

unlike my first wife who I would forewarn that I had sharpened the blunt kitchen knives but I could also guarantee she would later be making a dash for our first-aid cupboard for the plasters.
