From f35f313adc6718c1cde1c4581d08bce070834599 Mon Sep 17 00:00:00 2001 From: mmcw-dev Date: Tue, 27 Feb 2018 23:57:56 -0500 Subject: [PATCH] Lomo bottom screw is ready to re-print. Fixed threading on outer thread, added nubs instead of the simple hex design. Needs internal threading, which will depend on the outer piece. --- models/lomo_bottom_screw/lomo_bottom_screw.scad | 16 +++++++++++----- 1 file changed, 11 insertions(+), 5 deletions(-) diff --git a/models/lomo_bottom_screw/lomo_bottom_screw.scad b/models/lomo_bottom_screw/lomo_bottom_screw.scad index bdaeffc..593282c 100644 --- a/models/lomo_bottom_screw/lomo_bottom_screw.scad +++ b/models/lomo_bottom_screw/lomo_bottom_screw.scad @@ -3,14 +3,20 @@ include <../../libraries/threads.scad>; module base () { $fn = 100; + NUBS = 6; union() { translate([0, 0, -15])cylinder(r = 8.45, h = 20, center = true); - translate([0, 0, -24.5])cylinder(r = 11.1, h = 9.5, center = true, $fn = 6); + //hex version + //translate([0, 0, -24.5]) cylinder(r = 11.1, h = 9.5, center = true, $fn = 6); + translate([0, 0, -24.5]) cylinder(r = 19 / 2, h = 9.5, center = true); + for (i = [1 : 6]) { + rotate([0, 0, i * (360 / NUBS)]) translate([0, 19 / 2, -24.5]) cylinder(r = 3.2 / 2, h = 9.5, center = true); + } } } module lomo_bottom_screw () { - //base(); + base(); difference () { //outer screw translate([0, 0, -7.1]) metric_thread (diameter=10, pitch=1.5,thread_size = 1.6, length=27.1); @@ -29,7 +35,7 @@ difference() { import("./lomo_part_half.stl"); //translate([200, 0, 0]) cube([400, 400, 400], center = true); } -rotate([0, 0, t]) difference() { - color("green") lomo_bottom_screw(); - //translate([-100, 0, 0])cube([200, 200, 200], center = true); +translate([0, -0.25, -0.05]) rotate([0, 0, t]) difference() { + //color("green") lomo_bottom_screw(); + //translate([-20, 0, 0])cube([40, 40, 200], center = true); }
