Early <a href="https://pixelfed.social/discover/tags/3DPrinted?src=hash" class="u-url hashtag" rel="nofollow noopener noreferrer" target="_blank">#3DPrinted</a> prototype of <a href="https://pixelfed.social/discover/tags/Classic?src=hash" class="u-url hashtag" rel="nofollow noopener noreferrer" target="_blank">#Classic</a> <a href="https://pixelfed.social/discover/tags/IonicCapital?src=hash" class="u-url hashtag" rel="nofollow noopener noreferrer" target="_blank">#IonicCapital</a> from a few years back using a <a href="https://pixelfed.social/discover/tags/Prusa?src=hash" class="u-url hashtag" rel="nofollow noopener noreferrer" target="_blank">#Prusa</a> <a href="https://pixelfed.social/discover/tags/MKS4?src=hash" class="u-url hashtag" rel="nofollow noopener noreferrer" target="_blank">#MKS4</a> <a href="https://pixelfed.social/discover/tags/3DPrinter?src=hash" class="u-url hashtag" rel="nofollow noopener noreferrer" target="_blank">#3DPrinter</a>.<br>
<br>
The length of the <a href="https://pixelfed.social/discover/tags/volute?src=hash" class="u-url hashtag" rel="nofollow noopener noreferrer" target="_blank">#volute</a> from end-to-end is more than 10". I rotated the <a href="https://pixelfed.social/discover/tags/voluteSlab?src=hash" class="u-url hashtag" rel="nofollow noopener noreferrer" target="_blank">#voluteSlab</a> 45° on the printer bed, and by the grace of <a href="https://pixelfed.social/discover/tags/Pythagoras?src=hash" class="u-url hashtag" rel="nofollow noopener noreferrer" target="_blank">#Pythagoras</a>, I was able to print it inside the 8" build envelope of the MKS4.<br>
<br>
This prototype has many imperfections, and some elements are just plain "wrong" -- like the curved inside of the volute channel (instead of flat).<br>
<br>
The <a href="https://pixelfed.social/discover/tags/ovolo?src=hash" class="u-url hashtag" rel="nofollow noopener noreferrer" target="_blank">#ovolo</a> is lacking <a href="https://pixelfed.social/discover/tags/eggsAndDarts?src=hash" class="u-url hashtag" rel="nofollow noopener noreferrer" target="_blank">#eggsAndDarts</a> because I had not yet made the distinction between a <a href="https://pixelfed.social/discover/tags/tectonicSurface?src=hash" class="u-url hashtag" rel="nofollow noopener noreferrer" target="_blank">#tectonicSurface</a> on which the <a href="https://pixelfed.social/discover/tags/decorativeElements?src=hash" class="u-url hashtag" rel="nofollow noopener noreferrer" target="_blank">#decorativeElements</a> rest, and a <a href="https://pixelfed.social/discover/tags/virtualSurface?src=hash" class="u-url hashtag" rel="nofollow noopener noreferrer" target="_blank">#virtualSurface</a> that encloses the decorative elements. My calculations always seemed to differ from those in <a href="https://pixelfed.social/discover/tags/Scarlata?src=hash" class="u-url hashtag" rel="nofollow noopener noreferrer" target="_blank">#Scarlata</a>'s book. But as the physical <a href="https://pixelfed.social/discover/tags/3DPrint?src=hash" class="u-url hashtag" rel="nofollow noopener noreferrer" target="_blank">#3DPrint</a> shows, it is perfectly OK to go for a minimalistic look — even if it means a ribbon shorn of <a href="https://pixelfed.social/discover/tags/braids?src=hash" class="u-url hashtag" rel="nofollow noopener noreferrer" target="_blank">#braids</a>. It's the distinctive design of the core tectonic elements that has the greatest impact.<br>
<br>
I used brown silk filament for the braids, because, why not? For this prototype, I printed them separately and glued them to the <a href="https://pixelfed.social/discover/tags/scroll?src=hash" class="u-url hashtag" rel="nofollow noopener noreferrer" target="_blank">#scroll</a>.<br>
<br>
Also, the scrolls are misshapen because I had not yet figured out the correct geometry. It would be another 4 years of tinkering with my <a href="https://pixelfed.social/discover/tags/CAD?src=hash" class="u-url hashtag" rel="nofollow noopener noreferrer" target="_blank">#CAD</a> design to finally get my <a href="https://pixelfed.social/discover/tags/Eureka?src=hash" class="u-url hashtag" rel="nofollow noopener noreferrer" target="_blank">#Eureka</a> moment — and that's when I decided to start this series.
