If you lose your shirts collar stays just print an extra set. You can scale these longer, shorter, wider, and/or narrower to suit your needs. As a nice custom touch, you can add a monogram with the text feature ion the Bambu slicer. If so, I recommend “modifier” part type and have the text on the bottom (build plate) to get a nice flat embedded finish - don't forget to make the text a different color and I recommend choosing embedded depth of the text of 0.4mm to get two layers for sharp text.
