13 mm M&M-Style Candy Discs, 20 Pieces

Twenty M&M-style candy discs for fake-sprinkle piles and display work: 13 mm across, 5 mm thick, rounded at the edge and topped with a raised white "m". There is no host part, thread or bore to match here, so the number that decides whether a batch works is the disc diameter — 13 mm — measured against the surface, bowl or tray it is going onto.

Sizes (viewer labels: Red Candies, Yellow Candies, Green Candies, Blue Candies, Orange Candies, White m Letters)

• Disc diameter: 13 mm on every piece.
• Thickness: 5 mm at the body; the raised "m" adds 0.5 mm.
• Raised "m": 0.5 mm tall, white, and its own colour region.
• Quantity: 20 pieces in a 5 × 4 grid.
• Spacing: about 16 mm centre to centre, so no two pieces touch. Whole batch footprint on the plate is roughly 77 × 61 mm.
• Colours: five candy regions — red, yellow, green, blue and orange — plus white "m" lettering.

Each candy is a separate loose piece sitting flat on its base, so the batch prints with no supports. The candy colours and the white lettering are separate regions of the print, which means a colour print needs filament changes for the candy colours and another for the white "m"; a single-colour batch will lose the M&M look entirely.

What to check before printing

• The "m" is only 0.5 mm tall and is white as its own colour region. For a clean white letter, switch filament at the layer where the "m" starts, about 5 mm up; at that height it prints as a thin top layer. Without that swap, the lettering prints in the loaded colour and loses contrast.
• At 13 mm across and 16 mm spacing the first layer has plenty of room, but 20 small loose pieces still reward a brim or a slow first layer so nothing gets knocked loose.

What these are not: decoration only — not edible, not real candy, and not a substitute for real sweets on food. They are also not a match for anything with a fixed 14 mm or 15 mm recess; at 13 mm they will sit loose in it.
