For those who want to tackle this as a DIY project, the difficulty will be generating the CAD file just to get a fab shop to speak to you. Then the problem is finding a fab shop that is willing to take on such a miniscule production run.
This is an example of the contents of a DXF file that I used with Send-Cut-Send. The part is sheet metal and the green line indicates the bend they should make. Worked out well.
The bend point is calculated in sheet metal CAD software, where the thickess and the K-factor can be entered (https://sendcutsend.com/blog/what-is-k-factor-in-bending-terminology).
