Drain pipe project

Needed to attach a 45 degree angled drain pipe to a wooden post, and came up with this.
The idea is that the bracket is mounted on the wooden post, with the flat extending face pointing upwards, and then the knob is inserted in the upward facing side, with the wide end at the top, and then the angled triangle is fit on top of the wide knob, and screwed in place with a 3x20mm screw. Finally the PipeHolder is screwed onto the angled triangle using a 4x25 mm screw.
This should let the knob turn
