Im super pleased how it turned out in filament! Just ordered the plate in 6061 aluminum from JLCCNC. Cost me less than $300 in total for this project.
I attached my ****ty technical drawing and STEP file incase it benifits anyone else. Note that if your holes aren't drilled perfectly they may need some adjusting to fit properly.
