This is a simple print without supports (print in orientation as downloaded) that you can screw into the underside of a desk or table. It should fit most tape measures out there, I use a Stanley tape measure and it fits great. I used drywall screws because I had them handy, but there are a number of screws that will work. The screw holes themselves are 3mm in diameter, and the overall channel for the screws is about 10mm in diameter, so any screw with a head less than that will work.
