There are holes on the arm attachment end and the plate. You can use M2 Machine Screws with a nut. Or if you don't have that around you could use just about anything else such as some wire and feed it through the holes and twist the wire tight.
This is a tablet stand I specifically designed for my iPad mini with it's super thick case. Any tablet should work. This will allow you to mount it to your Fitness Reality 4000MR rowing machine. Possibly other Fitness Reality equipment or other equipment which have a place to mount that is no more than 40mm wide or about 1.6 inches wide. It's 20 mm deep but, that can be extended if you use longer bolts.
No special supports needed.
Print at 0.3mm for faster print and 50% infill for strength.
