Hitchhiker's Guide to the Galaxy Symbol Fridge Magnet

thingiverse

This uses a 18mm ceramic magnet with a height of 3mm. Printed in Warhorse blue PLA and a Silk Black PLA from another manufacturer using PrusaSlicer's color change feature, which allowed me to manually switch filaments at the right layer. I printed two: One in blue with a silver silk black layer, and one in silk black with a blue layer. The filament should be swapped just before bridging the 3mm gap over the hole for the magnet and again just before the symbol starts at 3.6mm. During the first color change, I inserted the magnet into the hole, ensuring it sits flush inside.
