Dishwasher Cat Magnet

My wife wanted a magnetic clean/dirty indicator for the dishwasher. We both like cats so I searched here on Thingiverse for cat silhouettes. I found the designs by @wslab and my wife chose Black Cat 10. I downloaded the .stl and was able to hack it in FreeCAD (basically traced it into a sketch) to 5mm thick extrusion, "CLEAN" and "DIRTY" text strings (using Arial Black) cut 2mm out of the front and back, and two voids inside for magnets. The magnets I used are 15mm x 6.5mm x 3mm, that I purchased from Amazon here (not an affiliate link): https://www.amazon.com/gp/product/B077BWCC8D/ref=ppx_yo_dt_b_asin_title_o07_s00?ie=UTF8&psc=1 Any magnet of the same dimensions should work. I added a chamfer the bottom edge to use to help grip when removing the magnet, but without fingernails it doesn't seem to work as intended.

I sliced it in [Slic3r PE v 1.42.0 beta1](https://github.com/prusa3d/Slic3r/releases/tag/version_1.42.0-beta1) at 0.2mm layer thickness. Filament color changes after 2mm,
