I&#8217;d been wanting to scan my nose cone for ages. Mainly with the intention of modeling and printing a &#8220;bracket&#8221; for the number plate &#8211; which flaps around a bit on its velcro mount.<\/p>\n\n\n\n<p>But the first thing to do was get a scan.&nbsp;<\/p>\n\n\n\n<p>I tried a few different ways of scanning, structure-laser and IR textured\/non-textured with the Shining 3D HX and textured IR scanning with the Einstar.&nbsp;<\/p>\n\n\n\n<p>As expected, the structured-laser scan was by far the better scan &#8211; as long as I scan in low light and with loads of markers. Next came the rapid and textured scan with the HX. Then propping up the rear was the Einstar. I need to spend more time with the Einstar &#8216;cos I&#8217;m not getting the results I&#8217;ve seen others achieve. After scanning the nose cone, I measured across the 7 logo on the front and across the ~200mm the Einstar with 2mm short. The structure-light HX scan was within 0.1mm and the rapid scan about 0.5mm. Though both of those measurements are well within a confirmation-biased measurement and should be taken with a large pinch of salt (I may not be as objective a tester as I should be!).<\/p>\n\n\n\n<p>Here&#8217;s a picture of the nose-cone covered in scanning markers&#8230;<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1536\" height=\"2048\" data-attachment-id=\"10903\" data-permalink=\"https:\/\/purplemeanie.co.uk\/img_0508-2\/\" data-orig-file=\"https:\/\/purplemeanie.co.uk\/wp-content\/uploads\/2025\/05\/IMG_0508-scaled.jpeg\" data-orig-size=\"1920,2560\" data-comments-opened=\"1\" data-image-meta=\"{&quot;aperture&quot;:&quot;1.78&quot;,&quot;credit&quot;:&quot;&quot;,&quot;camera&quot;:&quot;iPhone 16 Pro&quot;,&quot;caption&quot;:&quot;&quot;,&quot;created_timestamp&quot;:&quot;1748095321&quot;,&quot;copyright&quot;:&quot;&quot;,&quot;focal_length&quot;:&quot;6.7649998656528&quot;,&quot;iso&quot;:&quot;100&quot;,&quot;shutter_speed&quot;:&quot;0.01&quot;,&quot;title&quot;:&quot;&quot;,&quot;orientation&quot;:&quot;1&quot;}\" data-image-title=\"IMG_0508\" data-image-description=\"\" data-image-caption=\"\" data-large-file=\"https:\/\/purplemeanie.co.uk\/wp-content\/uploads\/2025\/05\/IMG_0508-1536x2048.jpeg\" src=\"http:\/\/purplemeanie.co.uk\/wp-content\/uploads\/2025\/05\/IMG_0508-1536x2048.jpeg\" alt=\"\" class=\"wp-image-10903\" srcset=\"https:\/\/purplemeanie.co.uk\/wp-content\/uploads\/2025\/05\/IMG_0508-1536x2048.jpeg 1536w, https:\/\/purplemeanie.co.uk\/wp-content\/uploads\/2025\/05\/IMG_0508-450x600.jpeg 450w, https:\/\/purplemeanie.co.uk\/wp-content\/uploads\/2025\/05\/IMG_0508-768x1024.jpeg 768w, https:\/\/purplemeanie.co.uk\/wp-content\/uploads\/2025\/05\/IMG_0508-1152x1536.jpeg 1152w, https:\/\/purplemeanie.co.uk\/wp-content\/uploads\/2025\/05\/IMG_0508-scaled.jpeg 1920w\" sizes=\"auto, (max-width: 1536px) 100vw, 1536px\" \/><figcaption class=\"wp-element-caption\">SV Nose Cone covered in reflective 3D scanning markers<\/figcaption><\/figure>\n\n\n\n<p>Anyway, here&#8217;s the model if you want to download and play with it.

call complete. It&#8217;s very hole-y.<\/p>\n<p>What it really needs is a few more scans to fill in the holes. But you get to a point where you&#8217;ve had enough really. I did a few scans to start with, to dial in the ambient lighting (needed to be very low) and to decide on whether the metallic paint scanned best as a normal object, black or shiny. Then needed to decide if it needed some scanning spray. In the end I found I got the best results scanning it with some grey fogging spray and on the reflective setting.\u00a0<\/p>\n<p>So once you&#8217;ve spent a couple of hours patting around with all that, I really ought to give up for the day and come back fresh in the morning. But I needed the Seven out of the garage for the scanning and that meant bringing it back in and taking it out again the next day. So I cracked on.<\/p>\n<p>It took about 3 scans to capture the whole of the nose-cone. Plus trying the rapid scanning and the Einstar. So in the end I wasn&#8217;t in the mood for hole filling&#8230; it&#8217;ll be fine for what I need it for. If someone wants to may me a few hundred quid for a full scan, then I now know what settings I&#8217;ll need \ud83d\ude42\u00a0<\/p>\n<p>Part of the problem is that Shining-3D&#8217;s workflow is a bit hit and miss when it comes to jumping from the end of their workflow, i.e. a meshed object, back to the beginning, scanning. Which means by the time I&#8217;ve got a fully meshed model (and can see exactly how much data I&#8217;ve got) it then becomes a faff to go back to the scanning stage for some fill ins.<\/p>\n<p>Hey
