The file 'Butterfly Magnet 3D Printer Model' is (stl) file type, size is 193.4KB.
I scaled it down 50% and added spaces for 3 3x1mm magnets. I had to bulk up the body to fit the magnets. You will need to add a PAUSE at the layer before the spaces are covered to add the magnets.
I also added a M600 filament change after the flat layer to give it a nicer look.
Like the original, the wings and antennae can be positioned when hot off the build plate, or later using a heat gun or boiling water to soften the PLA.
v2 - Added a bit more space for the magnets. Should be easier to insert.
Here is an example of the magnets that work with this: https://www.amazon.com/TRYMAG-Magnets-Whiteboard-Billboard-Hobbies/dp/B09MQ3JXLV/ref=sr_1_1_sspa?crid=19CBW53ISMUXT&keywords=3mm%2Bmagnets&qid=1703716913&sprefix=3mm%2Bmagnets%2Caps%2C291&sr=8-1-spons&sp_csd=d2lkZ2V0TmFtZT1zcF9hdGY&th=1
