I had lost the original caps, which were too loose and could be easily removed, and the foam wrapped around the bar was beginning to leave.
I designed these caps on Fusion 360, they can be tightened once it's in the handlebar, thanks to a M3 screw and an insert.
It works very well and I don't think they will come off.
You'll need a M3 screw (~27mm long) and a M3 heat insert (∅4mm, length 3mm).
