Arrow fletching marking jig (parametric)

prusaprinters

<h3>Why?</h3><p>This is a small tool made for sliding onto your arrows so you can use a mechanical pencil or marker to draw lines for attaching stick-on type fletchings, such as XSWings, Spin Vanes, Spinwings etc.</p><h4>Parametric</h4><p>There are two example STLs included, but the intended use is opening the OpenSCAD file and changing the settings to suit your arrows and preference. All options are editable:</p><ul><li>Arrow shaft diameter</li><li>Outer diameter</li><li>Length of marking grooves</li><li>Width of marking grooves</li><li>Number of marking grooves</li><li>Thickness of support between marking grooves</li><li>Open or closed type base</li><li>Nock aligner height and width</li><li>Length of base before first marking groove starts</li></ul><p>There are comments next to each parameter in the .scad file explaining their use.</p><h4>There is a choice of open or closed type:</h4><p><strong>Open type</strong> is for sliding on from the pile end, where nocks are significantly wider than shaft diameter, or where alignment with the nock direction isn't critical, ie: you have pin nocks and can rotate them to suit afterwards. There is a groove marked in the bottom of the jig if you wish to line up with your nocks anyway.</p><p><strong>Closed type</strong> is for when you cannot rotate your nocks freely. You can choose to have a nock aligner in the bottom of the jig onto which you push the nock as if it were the string, ensuring correct alignment.</p>
