Casting Plug

A1 / A1 Mini Optimized: This profile has been tuned specifically for the Bambu A1 series. It utilizes Vibration Compensation and calibrated Flow Rates to ensure the edges are sharp and the weight is solid.
Custom Density Infill: I’ve set this to a high-percentage Gyroid Infill ($40\text{%}-60\text{%}$ depending on your desired weight) to give it a realistic "thump" when it hits the ground. It’s balanced to fly straight and true through the air.
Reinforced Eyelet: The attachment point is printed with 5 Wall Loops, making it tough enough to withstand hundreds of power casts without snapping off your line.
Precision Layering: Printed at a $0.16\text{ mm}$ layer height for a smooth surface that won't snag on grass or weeds.
Anti-Roll: The pyramid shape prevents the weight from rolling back toward you or down hills after a long cast.
High Visibility: Designed to be printed in one solid, bright color (like Neon Orange or Yellow) so you can spot your landing mark from $50\text{ yards}$ away.
Print-and-Go: No supports needed! The $45\degree$ angles of the pyramid are well within the A1's overhang capabilities, resulting in a clean finish on all sides.
