Tired of fighting uneven copper plating? This servo-driven rotator solves the #1 problem in electroforming — spotty coverage from items sitting still in the bath. Slow, even rotation means consistent thickness, smoother surfaces, and far less rework.
What you get — a complete print-and-build kit of 23 STL files for a 10.5″ tank-clamp rotator with brushing house, servo base, donut mount, tunnel guides, and tank clamps. Bring your own off-the-shelf servo + 3D printer.
Skill level — if you can run a 3D printer and follow a build video, you can build this. No machining, no welding.
