A versatile extuder motor indicator crafted from a scaled-down 25% _3D Printable Jet Engine's_ fan by **CATIAV5FTW**, available in three versions: with an integrated cone, with a separate cone featuring a spiral strip, or without a cone.

Each version has its unique characteristics, including a brim around blades to enhance adhesion for the ones with brims, while the others require careful removal of excess material with an xacto knife due to lifting from the bed. Versions featuring a brim boast a 0.1 mm high brim to ensure better adhesion, which can be removed later if desired. A spacer is also included to position the indicator further away from the motor for users with 3 mm thick magnets (8x3 mm is a standard size). This spacer is designed to fit snugly inside the base of the fan's cavity for easier alignment. Recommended printing settings include a layer height of 0.05-0.1 mm for optimal results. To complete this project, you'll need an 8x3 mm magnet and CA glue (or similar adhesive) to secure the magnet, spacer, and fan together. Be cautious not to apply excessive glue to avoid bonding the fan to the extruder motor.
