Wrist Calculator Circular Slide Rule

prusaprinters

<p>This slide rule bracelet is best printed at .1mm layer height and no infill.</p><p>Infill, such as gyroid, may be used to create an aesthetic as light shines through the thin rings. For opaque materials, zero infill works well.</p><p>Using temperature and UV sensitive filaments can increase the features of this calculating device.</p><p>The two parts snap together. Some scraping or sanding may be necessary, especially if printing with multiple materials (available from the openSCAD).</p><p>The dense marks require a large print (a neckless instead of a bracelet) or a small nozzle.</p><p>When printing with dual material and .25 nozzle I found the best marks were with a width of .3mm and external perimeter of .15, .25 normal parameter and 3 shells. This allows for a ring in the marking area. Also, I used .003 extra on restart because there are many small retractions for the marks.</p><p>Creative Commons non-commercial, share alike 2021.</p><p>Share and nJoy maths!</p>
