Simple toroid winding wire holder

prusaprinters

<p>Simple parametric design to hold wire to wind a toroid easily.</p> <p>The end cutouts are inset the same as the width, so the default version is 30mm long and 5mm wide (for a 6mm toroid hole) so wire held for one complete wrap is</p> <p>2<em>(L-(W</em>2)) = 2*(30-10) = 40mm wire per wrap.</p> <p>One turn on my particular Toroid is 2* (5.33mm + 2.33mm) = approx 16mm rounded up</p> <p>So to wrap 100 turns I need 1600mm or 40 turns on the spool.</p> <p>Now simplified so you just enter how much wire you want to hold for one COMPLETE turn on the spool, the spool thickness is taken into account as well.</p> <p>My first customizer job, to see how it works..</p> <p>edit:seems the customizer is broken, so you need to have openscad (Get it anyway!) <a href="/groups/thingiverse/forums/site-issues-and-feedback/topic:26898">https://www.thingiverse.com/groups/thingiverse/forums/site-issues-and-feedback/topic:26898</a></p> <p>I will upload some different sizes anyway.</p> <p>done, format is wire_length_per_turn,spool_width,spool_thickness</p> <p>So for 1600mm of wire (100 turns) on my 6mm ID toroid, I need the 50_5_1 version, and do 32 turns of wire on it, or the 100_5_2 version and do 16 turns, my wire is thin so the short version will be fine.</p> <p>Photos show 32 wraps on the spool for 1.6m wire and then what remains after wrapping 100 turns.</p> Category: Tool Holders & Boxes
