Assembled Piston Guide with Spool

// --- PARAMETERS --- piston_d = 21.5; // Diameter of the cube/piston sleeve_id = 22.0; // Inner diameter of the guide wall_t = 2.0; // Thickness of the guide wall spool_d = 12.0; // Diameter of the winder spool spool_h = 8.0; // Height of the winder spool // --- MODULES --- // 1. The Piston (The Cube/Lift part) module piston() { translate([0, 0, 5]) difference() { cube([piston_d, piston_d, 20], center=true); // Hole at the bottom for fishing line translate([0, 0, -8]) rotate([0, 90, 0]) cylinder(h=piston_d, r=1, center=true); } } // 2. The Guide Sleeve module guide_sleeve() { difference() { cylinder(h=50, d=sleeve_id + (wall_t*2), center=true); cylinder(h=51, d=sleeve_id, center=true); } } // 3. The Servo Spool module servo_spool() { difference() { union() { cylinder(h=spool_h, d=spool_d); cylinder(h=spool_h + 2, d=spool_d + 4); // The rim to hold line } // Center hole for servo horn cylinder(h=spool_h + 5, d=5, center=true); } } // --- RENDER --- // Uncomment the line you want to render/export // piston(); // guide_sleeve(); servo_spool();

Parameters

Every value above is a live dimension. Open a model like this in the editor and each one becomes a slider you can drag before exporting.
