Screw holders for CURT Trailer Hitch License Plate Holder

I needed a way to mount screws through a license plate on the CURT Trailer Hitch License Plate Holder ( https://www.amazon.com/dp/B0009YIE14?psc=1&ref=ppx_yo2ov_dt_b_product_details ) using coarse screws I got at Menards ( https://www.menards.com/main/tools/automotive/automotive-accessories/license-plate-frames/cruiser-reg-license-plate-frame-ultimate-fastener-kit-stainless-star-pin/81500/p-1444428007719-c-1527167451378.htm ).

These work perfect for this application.  I printed in PLA with 40% infill.  I did need to thread these in a vise before using but that was simple to do.
