Very simple bracket to mount a standard 50mm power supply under a delta printer. The rendered STL is fit for my BIQU Kossel Plus along with Peaberry's Kossel Base Stands and my Parametric Kossel Base Panels. If you need a different size, this bracket is pretty flexible in Customizer.
The crossbeam between the two uprights isn't structural at all -- it's just to maintain the spacing when attaching the uprights to the 2020. In the rendered STL and the bracket I use IRL, I made it so thin as to be very flexible to save material and print time..
This is a simple part with no supports or weird angles. You should be able to print this pretty easily on almost anything.
Three cubes minus four cylinders -- not much to this one.
