About this 3D model

I ordered two sets of bench dogs with finishing cones from America. My previous project also required finishing bridges, but their unavailability in the Czech Republic necessitated a 3D printing solution. My initial intention was to use a standard screw, but Rockler, predictably, utilizes a non-metric thread. Sourcing a 5/16″-18TPI threaded screw proved quite challenging, hence the 3D printing. I maximized the screw head size to fit within the recess in the base, ensuring easier hand tightening and a larger contact area with the bench cookie. Two files are attached: one with a 0.15 offset (easily removable from the screw) and one with a 0.10 offset (for a secure fit).
