https://stream.echo6.co/videos/watch/6645f7d3-45ff-4d51-8223-4a1eb9c03e50 I'm going to avoid doing too many 3D printed projects because not everyone has access to a 3D printer. The openscad script is down below. I used natural/transparent PLA. Main openSCAD website here:- https://www.openscad.org/ To find the slow colour change RGB LEDs:- https://www.ebay.com/sch/i.html?_from=R40&_nkw=100pcs+5mm+diffused+led+rgb+slow&_sacat=0&_sop=15 If you enjoy these videos you can help support the channel with a dollar for coffee, cookies and random gadgets for disassembly at:- http://www.bigclive.com/coffee.htm This also keeps the channel independent of YouTube's advertising algorithms allowing it to be a bit more dangerous and naughty. Copy and paste the script below into openscad to make a crystal. //Big Clive 21/Jan/2020 LED quartz difference(){ union(){ difference(){ union(){ //six sub crystals rotate([45, 0, 0]) cylinder(h =80, d1 = 30,d2 = 20,$fn=6); rotate([45, 0, 0]) translate([0,0,80]) cylinder(h =10, d1 = 20,d2 = 0,$fn=6); cylinder(h =80, d1 = 30,d2 = 20,$fn=6); rotate([45, 0, 60]) translate([0,0,80]) cylinder(h =10, d1 = 20,d2 = 0,$fn=6); cylinder(h =80, d1 = 30,d2 = 20,$fn=6); rotate([45, 0, 120]) translate([0,0,80]) cylinder(h =10, d1 = 20,d2 = 0,$fn=6); cylinder(h =80, d1 = 30,d2 = 20,$fn=6); rotate([45, 0, 180]) translate([0,0,80]) cylinder(h =10, d1 = 20,d2 = 0,$fn=6); cylinder(h =80, d1 = 30,d2 = 20,$fn=6); rotate([45, 0, 240]) translate([0,0,80]) cylinder(h =10, d1 = 20,d2 = 0,$fn=6); cylinder(h =80, d1 = 30,d2 = 20,$fn=6); rotate([45, 0, 300]) translate([0,0,80]) cylinder(h =10, d1 = 20,d2 = 0,$fn=6); //main central crystal translate([0, 0, 0]) cylinder(h =100, d1 = 50,d2 = 20,$fn=6); //main crystal tip translate([0, 0, 100]) cylinder(h =10,d1=20,d2=0,$fn=6); } //remove central crystal core translate([0, 0, -1]) cylinder(h =101.1, d1 = 48,d2 = 18,$fn=6); //remove centre crystal tip translate([0, 0, 100]) cylinder(h =9,d1=18,d2=0,$fn=6); //six sub crystal core removal rotate([45, 0, 0]) translate([0,0,0]) cylinder(h =80.1, d1 = 28,d2 = 18,$fn=6); rotate([45, 0, 0]) translate([0,0,80]) cylinder(h =9, d1 = 18,d2 = 0,$fn=6); cylinder(h =80.1, d1 = 28,d2 = 18,$fn=6); rotate([45, 0, 60]) translate([0,0,80]) cylinder(h =9, d1 = 18,d2 = 0,$fn=6); cylinder(h =80.1, d1 = 28,d2 = 18,$fn=6); rotate([45, 0, 120]) translate([0,0,80]) cylinder(h =9, d1 = 18,d2 = 0,$fn=6); cylinder(h =80.1, d1 = 28,d2 = 18,$fn=6); rotate([45, 0, 180]) translate([0,0,80]) cylinder(h =9, d1 = 18,d2 = 0,$fn=6); cylinder(h =80.1, d1 = 28,d2 = 18,$fn=6); rotate([45, 0, 240]) translate([0,0,80]) cylinder(h =9, d1 = 18,d2 = 0,$fn=6); cylinder(h =80.1, d1 = 28,d2 = 18,$fn=6); rotate([45, 0, 300]) translate([0,0,80]) cylinder(h =9, d1 = 18,d2 = 0,$fn=6); } //Second solid additions //Add base cone translate([0,0,3]) cylinder(h =45, d1 = 100,d2 = 7,$fn=6); //led plinths rotate([45, 0, 0]) translate([0,0,30]) cylinder(h =5.5, d1 = 20,d2 = 8,$fn=20); rotate([45, 0, 60]) translate([0,0,30]) cylinder(h =5.5, d1 = 20,d2 = 8,$fn=20); rotate([45, 0, 120]) translate([0,0,30]) cylinder(h =5.5, d1 = 20,d2 = 8,$fn=20); rotate([45, 0, 180]) translate([0,0,30]) cylinder(h =5.5, d1 = 20,d2 = 8,$fn=20); rotate([45, 0, 240]) translate([0,0,30]) cylinder(h =5.5, d1 = 20,d2 = 8,$fn=20); rotate([45, 0, 300]) translate([0,0,30]) cylinder(h =5.5, d1 = 20,d2 = 8,$fn=20); //cable entry translate([0,-35,10]) rotate([45, 0, 0]) sphere (d=10,$fn=20); } //Second removals //Inner base area translate([0,0,2]) cylinder(h =45, d1 = 100,d2 = 6,$fn=6); //base removal cube translate([-50,-50,-47]) cube ([100,100,50]); //LED hole removal rotate([45, 0, 0]) translate([0,0,26]) cylinder(h =10,d1=5,d2=5,$fn=20); cylinder(h =10,d1=5,d2=5,$fn=20); cylinder(h =10,d1=5,d2=5,$fn=20); cylinder(h =10,d1=5,d2=5,$fn=20); cylinder(h =10,d1=5,d2=5,$fn=20); cylinder(h =10,d1=5,d2=5,$fn=20); //main pillar LED hole translate([0,0,40]) cylinder(h =10,d1=5,d2=5,$fn=20); //cable entry translate([0,-35,10]) rotate([45,0,0]) cylinder(h =20, d1 = 4,d2 = 4,$fn=20); } Wed, 15 Apr 2026 13:46:24 GMT https://validator.w3.org/feed/docs/rss2.html PeerTube - https://stream.echo6.co https://stream.echo6.co/client/assets/images/icons/icon-512x512.png https://stream.echo6.co/videos/watch/6645f7d3-45ff-4d51-8223-4a1eb9c03e50 All rights reserved, unless otherwise specified in the terms specified at https://stream.echo6.co/about and potential licenses granted by each content's rightholder.
