Posting here in case this comes up in a search.
First one is done
Filament is Siraya PET-CF. 50% infill, 6 walls, 6 top and bottom layers and I added features to make it solid between the bottom of the coupling nut and the tool chest. I think these are ridiculously overbuilt.
Grade 5 1/2-13 coupling nuts, swivel leveling mounts, and 5/16-18 serrated flange bolts, all from McMaster. The mounts are rated to 3750 lb each and have a 2" stud.
Min height will be right about 4", I'd say max would be 5". That could easily be increased or decreased with adjusting the printed part or stud length.
The McMaster order was $141 and 2kg of filament was $63.
