EDF testing frame w/ variable pivot point and adjustable center of thrust

this is a frame that i designed to test micro EDF's thrust

i printed this using PLA on my anet a6 without supports

to build it you will need a file to reduce the tolerances
you will also need 2 m5 screw with corresponding nuts i used 50mm bolts but you can use whatever size you want greater than 20mm.
you will also need a set of scales.

i have also provided the fusion 360 project file so that you can modify it
