We're dealing with about 110 kg of copper: three nested spheres, 50 cm, 80 cm and 1.3 m in diameter, each made of 1.5 mm copper sheet. The largest sphere alone weighs about 72 kg. The challenge was to hold all of this, plus a fractal Merkaba at the centre, without any of them touching. They have to stay perfectly aligned, insulated from each other, and adjustable to the millimetre. The attached PDF (45 pages) and video are the answer. WHAT'S INSIDE • Three nested copper spheres (Ø500 / 800 / 1300 mm, 1.5 mm Cu: about 11 kg, 27 kg and 72 kg). That's 5 : 8 : 13, a Fibonacci sequence. Inside sits the Sierpinski Merkaba, driven at up to 5 kV and about 1.4 MHz. • Two lattice support towers (25 cm and 15 cm), each 3D-printed in one piece from polypropylene. Their struts follow 13 clockwise + 21 counter-clockwise spirals, again Fibonacci numbers, which makes them strong and light with very little material near the field. • Five joints (J1–J5). Each one clamps a sphere wall between insulating rings, so no metal passes from one sphere to the next. Under the big sphere, a Ø180 mm counter-ring spreads the load so the thin copper doesn't bend. • A height jack that can't rotate. One turn of the wheel moves the Merkaba exactly 1 mm. It sets and holds the 3 mm gap between the Merkaba and the inner sphere. WHY THESE MATERIALS • PTFE for everything near the rod and the Merkaba tips: it has the lowest loss at 1.4 MHz. • Polypropylene for the towers: it's strong and doesn't absorb water. • POM (Delrin) for the precision threads of the jack. VERIFIED The design was checked part by part: 120 solid parts, 0 overlaps, nothing passing through the copper, and nothing touching the Merkaba. 📄 The PDF includes: exploded and cut-away views, a technical drawing for every part (P1–P21), a 9-step assembly order, and a bill of materials ready for outsourcing. 🎥 The video shows step by step how everything fits together. 🔄 THIS IS A LIVING DOCUMENT The main principles are set, but I'm still iterating, especially on the height jack and a few smaller parts. When something changes, I'll upload the updated PDF here with a version number, so you'll always know which one is current.
