Anti-loss ring for rubber bumpers, used in motorbike top case racks (Givi)

thingiverse

You might recognize this, if you're an owner of a motorbike with a luggage rack... :-) I've frequently lost those small rubber bumpers intended for the top case, from the luggage rack of my motorbike. It's a Givi rack and it's perfect ... apart from the holes with which the rubber bumpers are held in place: these are produced just to large & they hardly clamp the rubber bumpers at all. So, I figured to do something about it & these 3D printed anti-loss rings are doing the job just fine. Please note: In case you don't have a 3D printer, you'd probably also be able to reach the same thing with the right washer, but those would need to be pretty thin, then - you'd preferably need to try and find washers of 0.5 mm thick, with 6,5 mm bore. Hope this helps! :-)
