CD Duplicator Picker Assembly Component

thingiverse

This component is engaged upon by a hard wire attached throught he small hole on the perimeter, this wire is then attached to a solenoid that uses a spring to return when not powered. The center hole is used for rotating upon. A spindle from a component below comes up through this center hole then is mounted to a plate using a screw through the metal spindle center. The three slots capture drop pins that come from above and are captured in holes that allow slight movement. The drop pins go below this washer and are captured in 3 similar but differently oriented slots. When the solenoid is powered the washer is pulled. The drop pins being captured in slots below are forced in an outward motion which wears on the inner most face of the washer's 3 slots. This component is typically made of nickle plated brass, though the replacements are being made of semi hardened nickle. I have issues printing this washer (at twice the thickness) due to the slot with the most thin outer wall not being printed in a perimeter and fluid style motion, instead a gap is left from where the printer motion fails to purely meet each other right at the thinest portion. I have made adjustments by adding rectangles to thicken the portion up but the slic3r or something still gives me the same g-code command when printing the piece. This piece was designed by the machine shop we hired to make us duplicates of the pieces we have and are wearing out. It was designed on 2d software then uploaded to 3d software and done with a CNC application in mind. I am uncertain how this can effect things. I am also uncertain how to easily make this part myself from scratch on tinker cad or with sketchup.
