Update 11/04/2024

First prototype PCB design consists of two coil setups, one of which is a single layer, the other being a two layer version, connected in series. Each coil is 6mm in diameter with a 0.15mm trace width/clearance, and approximately 9 turns per layer.

PCB design:

CAD model:

M2 bolts will be used to align and fasten the outer 'chamber' part over the center of the coil.

The two parts were printed on the Creality Halot Lite SLA 3D-printer using clear ABS-like resin.
