Twelve-Slice Cake Portion Marker
A 170 mm ring with 12 tapered blades, 10 mm tall, every 30°. Press it onto a frosted 6–9 in (150–230 mm) cake or pie to mark 12 even slices. The four quarter blades run almost to a 6 mm centre hole, so you can also cut 4 or 6 portions. It prints blade-edge-up with the flat ring on the bed, uses about 35 cm³ and needs no supports.
Twin-Comb Cake Layer Torte Guide
This standing comb post has 45°-gusseted shelves that hold a bread knife flat while you saw a cake into even layers. One face has shelves at 15, 30, 45, 60 and 75 mm and the other at 22.5, 37.5, 52.5 and 67.5 mm, so you turn the post around to get 7.5 mm steps. Order two and stand one on each side of the cake. Each post is 80 mm tall on a 56 x 40 mm foot, the shelves are 24 mm deep, and the 3.5 mm slot fits blades up to about 3 mm thick.
Flagged: a sharp edge or blade. Not for safety-critical use without independent engineering review.
