aquarium holder

I was very angry that the factory mounts did not hold the pipes perfectly at 90°, so I decided to print modified mounts, I simplified their design, and in some places reinforced them. But the threads of the M6 bolts did not hold (on the printed part), so maybe my work will be useful to those who have a 3D printer, for example: SLA... If you use the factory mount and the printed one (from the bottom), then a different angle appears ((((
