The part can be used on a Jung 245.07 dimmer if the original bracket for the cover is broken.
Other dimmers and covers will probably also fit.
I printed it for better stability, as shown in the screenshot from the slicer. The adhesion was sufficient for me.
I drilled off the flanges on the dimmer itself so that the defective part can be removed. I then fixed the printed new one in place with a few drops of superglue.
