Lamp Ring Add-On to fit onto light fixture

I found the hole in the top of the original Lamp https://www.thingiverse.com/thing:1745140 was too big for my Australian Fittings, so I designed this up in 123D Design to act as a way to mount the lamp mesh onto the light fitting. I printed my Lamp and adapter in clear PETG at 260 Celsius nozzle, and 90 Bed. I actually liked the fine mesh if strings between the diamond holes. It needed to be that hot as it was really not doing well enough at 230.
