Magnetic holders that can handle 1 inch

[subarcticreef]

I'm in the process of ordering a new tank made of 1 inch acrylic. I want to avoid suction cups for the attachment of pumps etc and use magnets instead. But finding such magnetic holders is not easy. Is there anyone that help me here? Where can I find such holders?

I would start here, they do custom work too.
The holders might have to be made on a 3D printer.
