About this 3D model

This is the missing clamp bolt from the really cool modular mounting system by Ryan Huang (@yyh1002). See: 3d-print-modular-mounting-system-34864 The thread is a standard trapeziodal (power) screw per DIN103, and the size is TR12 x 3. I made this one 55mm long with a 3mm radius at the root.
