3D printer Halloween Costume

I wanted to be a 3D printer this Halloween!  What kind of printer?  HP!   (Halloween Pun!) 

The shirt was made with a cricut heat transfer vinyl.  The 3 D's were designed in prusa slicer with spots for magnets.  There are 3-4 Ø6 x 2 mm magnets in each and I have taped the opposing magnet to the back of the shirt.  

I've included the printer svg file, but I needed to clean it up in Cricut.
