Skylight this is not a bad find! But the OD to ID ratio is not right!
The OD of the light at the finning area is 36,7mm. So a 37mm OD o-ring would fit perfect and prevent ratteling. The main problem is, the finn spacing is 1,2mm but they are 1,7mm deep. This is the reason why it is not working with a round o-ring. Maybe if you use 2 flexible silicone o-rings ontop of each other.
But almost every flexible flat o-ring with a OD 28-37mm should fit, aslong the ID is ~3,5mm smaller than the OD.
A 1,2mm wide o.ring will fit perfectly but if you have one with a smaller OD (~28-33mm) you could get a 1,5mm one to fit (should fit after streching it to 33,3mm ID).
My main problem is to find one with this OD to ID ratio.

And it seems that now all Cometas are sold. The EU Warehouse is also showing Sold Out now.
