Ceiling coverplate Lamp shade boy

Thank you very much for publishing the lamp shade boy model. I used an Ikea sunneby to make this lamp. At first sight the body did not fit over the cylindrical shape of the sunneby fitting, it turned out you can unscrew the right part of this fitting and then it fits perfectly. 

Because I did not want to use a wooden plank and wanted to use two men I worked out this ceiling coverplate. The original Ikea closures that are used in the ikea cover pots fit in the finishing cap. To hang the ceiling cover I used a standard metal bracket of 95mm, the ceiling cover hangs on the sides
