Flame Dragon with Magnets
I used Blender 3.0.0 and PrusaSlicer 2.7.0 to fix the geometry and re-mesh.
In Blender, I made adjustments to eliminate fused sections (some artifacts were present due to the dragon feet, and residual internal geometry left over) then added holes for magnets (3mm dia x 2mm long cylindrical magnets). Then I exported the mesh to stl.
I imported the stl file to PrusaSlicer, I had the slicer fix errors, then reduce the polygon count. There were some minor errors that were causing problems, so I did some iterations of fixing errors in Blender and importing to PrusaSlicer. Afterword, I had PrusaSlicer create Gcode and confirmed that the sections were not fused.
I included the PrusaSlicer 3mf file that includes supports for the Dragon's chin and horns.
I used triple coextruded filament for a nice effect. The shiny ("silk") filament made of primary colors combined in an interesting way to make a part that changes color as you rotate the part.
I added the stl of the "hole" I used for introducing the magnet holes in Blender. The hole is too deep for a 3Dx2L magnet, so if you add holes, keep this in mind. It might be better to buy 3Dx1mm magnets.
To assemble the magnets into the holes, put a stack of two or three 3Dx1mm magnets on the back end of a 3/32 inch (2.5 mm) drill bit. Then put a drop of glue into the hole and use the drill bit to push the magnets into the hole. Use a paper towel to hold the magnet stack in place and slide the drill bit away -- this may take a little practice. Use the paper towel to wipe the bottom of the part smooth.
