Bicycle spoke ruler

prusaprinters

<p>A spoke ruler is an essential tool for a bike mechanic or wheel builder. Having the right length spokes is important to a fresh build, or replacing broken spokes. This is loosely based on my DT Swiss spoke ruler and just fits on a Prusa 250x200mm print bed and covers the range of spokes you're most likely to see.</p> <p>It measures the length, and has clearance notches to measure the most common spoke diameters.</p> <h3>Print instructions</h3><p>This <em>just</em> fits on a 250x220mm print bed, but you have to rotate it 40 degrees and turn off any skirt or brim. I also adjusted Infill/Fill Angle to 0 degrees which makes the infill close to the normal 45 degree since the part is rotated.</p> <p>I've included the SVG of the ruler portion which needs to be printed on paper to scale. I looked at creating the marks with the printer and a two color print, and the marks worked, but I couldn't do the text small enough and still have it legible. The paper print can be glued into place and works well, but I can't upload the PDFs that make printing it to size easy.</p>
