Mount box for a DETA 6242B four outlet powerpoint, it doesn't look like one exists (at least that I could find…) so 3D printing to the rescue! 

Recommend PETG and printing solid for rigidity, multiple models are provided with 20/25mm conduit entry sizes and top/bottom and side positions, however, if you need alternate entry sizes or positions please let me know and I will upload.  Holes for mounting are intended to be drilled to suit.
