DIY RMS Arms for AI Blades

[Rohirrimus]

Hello guys,
I am thinking of making arms for my new AI blades from regular Aluminium rails, and rail brackets:




Which would be perfect for me, strong, durable, industrial looking and best of all almost free.

My issue is I cannot for the life of me find the clamp part to secure it on the tank:






I don’t have any special requirement, just need it to fit the regular industrial rails, and to fit 12mm glass ( Red Sea reefer tank)

Thank you , any assistance is welcome

Surely someone could 3d print a fixing bracket to suit right?

I have a 3d printer but don’t know how to design it, and also don’t t trust it to hold
I have an alternative of screwing entire thing into the wall behind , but I would really prefer to have it tank mounted.

I think if I manage to find the part the 2 arms would be around 50$, much better than ridiculous 300 if buying aquarium specific, and also far more versatile ( those rails match the rails of other things like for example ender 3d printers, so can even add more attachments to them )
