The file 'Customizable Wire Access Grommet 1.41 3D Printer Model' is (stl,scad,zip) file type, size is 8.9MB.
This remix adds locking tabs to secure the top to the bottom, and to secure the bottom to the underside/backside of the hole. Also added a parameter to set the depth of the inside of the bottom part. I have not tested this yet! Please let me know if you have a problem.
The snaps are currently worthless--they snap off! Need redesigned.
