Protect your printer from nameless cosmic horrors lurking in dark and evil dimensions with this extruder visualiser in the shape of an Elder Sign!

Print instructions

I printed mine with PLA at 0.1 mm layer height. I placed the extruder-facing side down on the print bed, with supports under the main body (the magnet holder protrudes 2 mm below it).

Superglue an 8 mm neodymium magnet on to the little magnet holder button on the back of the symbol.

This size works well with my Prusa i3 MK2.5. Scale it if you need to.
