When setting up the print in the slicer, I set the end that receives the lock stud to the bed with a brim and tree supports. Also set the bottom ~25% with 5 walls and 75% infill. May be not really needed but didnt want to deal with the part breaking in use. For instructions on how to change walls/infill/etc on the same model see the video below. 

Heated up lock stud with heat gun and pressed into tool after removing all the support material.
