Temperature Blanket Shade Card

My mother has taken up crochet for a hobby and has been asking me to design or print related items. I am uploading a Temperature Blanket Shade Card with 12 available slots. It is blank so that you may add custom labels with a label maker. It measures 8.5in x 4.5in x 0.11in (~210mm x ~114mm x ~3mm). I designed it using Fusion 360 & have included an STL, 3MF, & STEP files for your remixing & printing delight.

Note: This is my very first upload to Thingiverse, please be kind in your feedback. I have only been tinkering with 3D Printing & Modeling as a hobby for a short time & mostly I am self taught.
