Reactor turning template

Set blank diameter, height, marble size, and socket ratio. Print a 1:1 carving template — dotted stock outline, solid carve silhouette, dashed marble seat at the top.

Physical top-ring Ø (ratio 0.584 × dowel). Full blank = 22.50 mm; narrower = smaller collar.

Opening = ratio × marble ⌀ (12.00 mm). Lower = narrower / shallower carve — marble size stays the same and sits more proud.

Top R: 6.57 mm

Throat R: 6.41 mm @ z=5.2 mm

Base R: 11.25 mm (= blank)

Socket depth: 2.71 mm
