I uploaded updated versions that I made here: 'Corrected' square GF Magnet hold-downs
I only did the square ones, as I had started similar ones a while back and liked the wooden inlays that were used here, so I included those.
@pubultrastar, I tried to figure out what scaling issue was in your original file but I couldn’t figure it out. No matter what tool I used to open it, they either went to 0.0001% or 1000% as others have reported.
