About this 3D model

I had problem unscrewing the hard-to-reach screw, so I 3D-printed this simple adapter. It works great; I recommend loosening the screw initially with a screwdriver and then removing it with this attachment using a power drill. So far, the attachment hasn't cracked even when loosening the screws. I printed it with support, vertically, wider end down, with 6 walls and infill.
