Tidal (Engagement) Ring

prusaprinters

<p>After an incredible 6 years together, it is finally time to ask my girlfriend for her hand in marriage. What better way than with my own parametrically designed 3D printed engagement ring??</p><p>The central design element, the wave, serves as a subtle visual reminder that a long-term relationship has its ups and downs. It takes compromises and flexibility to ensure a great and lasting partnership.</p><p>The design was parametrically written in Grasshopper for Rhino (see screenshot attached). Scaling the model is possible directly in the slicer, although I would recommend choosing the correct size from the uploaded files. I have added the most common sizes from 3 (14mm inner diameter) to 13.5 (22.6mm inner diameter).</p><p>&nbsp;</p><p><strong>Printing:</strong></p><p>The model was designed for standard FDM printing, with a 0.4mm nozzle. The attached images show the model printed with a 0.4 nozzle on the Prusa MK3S+ in Galaxy Silver PLA, eMarble PLA and white PLA. The results are very consistent with various materials. The standard Prusa Slicer profile “0.10mm DETAIL” works fantastically for this model. I do recommend applying glue stick to the bed, however, as the ring has relatively small base surface area.</p><p><strong>Nozzle:</strong> 0.4 is fine (0.25 is better)</p><p><strong>Layer Height:</strong> 0.1 mm</p><p><strong>Supports:</strong> None</p><p><strong>Infill:</strong> 100% (the model prints fast, so I prefer stability over saving time here)</p><p>&nbsp;</p>
