Lattice pie top cutter for 180-330 mm pie dishes

Gets a pie top done without a ruler or a sharp knife. Press the grid into rolled dough and it stamps out neat lattice pieces inside a round rim. It comes in four parts that fit together. Set the dish size, strip width and gap to match your bake.

Parts

  • cutter-quarter ×4 · PETG · As modelled and shown: press face down on the bed, blades pointing up. No supports.

    Four identical quarters, each 136 x 130 x 13.5 mm at the defaults. Each takes about 45 g and 63 min at 2 walls/15%, a quarter of the 181 g / 4 h 11 min total for the set. Each quarter has one dovetail tongue, one dovetail socket and a half pin channel on each seam, so any four printed copies go toge

Notes
PETG, chosen because it is tougher than PLA and handles warm washing water. At 2 walls and 15% infill the set is about 181 g and 4 h 11 min, or about 45 g and 63 min per quarter. Print one quarter per plate on a 180 mm bed, or two at a time on a 256 mm bed. Each window blade tapers from a 2.0 mm roo

Hardware

  • 4 × 1.75 mm filament offcut (PLA or PETG), about 15 mm long · One locking pin per seam. Push it into the hole at the rim along the seam line, then trim it flush. It stops the quarters sliding apart vertically. Pull it out with pliers to take the cutter apart for

Assembly

  1. Print four copies of cutter-quarter and cut four 15 mm pieces of 1.75 mm filament. Wash the quarters in warm soapy water before first use.
  2. Lay one quarter blades-up on the table. Each quarter has a dovetail tongue on one straight edge and a matching socket on the other.
  3. Slide the next quarter straight down onto it so its socket goes over the first quarter's tongue (the dovetails run vertically). Go around until all four are joined and the seams meet in a cross.
  4. At the rim, each seam has a small round hole halfway up the ring blade. Push a filament pin into each hole until it stops, about 15 mm in, and trim it flush. The quarters can no longer slide apart vertically.
  5. If the dovetails are too tight or too loose, reprint with the Joint clearance slider adjusted (0.1-0.4 mm).
  6. Roll the dough to the thickness you set (3.5 mm by default) on a floured board and dust the blades with flour. Turn the cutter blades-down onto the dough and press evenly with both palms until the blades touch the board.
  7. Lift the cutter off. Push any scraps left in the windows out through the openings in the press face with a finger or a chopstick, then slide the lattice top onto the pie.

Good to know

  • Not certified food-safe. 3D-printed layer lines can trap dough and bacteria. Take the pins out and wash the quarters by hand in warm (not boiling) soapy water, then dry fully. PETG softens around 75 °C, so keep it off hot dishwasher cycles and away from the oven.
  • It cuts a one-piece lattice-look top (square windows in a sheet of dough), not separate strips for weaving over and under.
  • The printed blades end in a 0.9 mm flat edge on a wall 1.3 mm thick at the tip, blunter than metal. Chilled, floured dough on a hard board cuts most cleanly; warm, sticky dough may need a second press or a knife tip at the corners.
  • Edge windows that would leave a scrap too small to push out (plate opening under 40 mm²) are left uncut, so the band near the rim is wider in some places.
  • The dovetail fit and the pin holes have only been checked as geometry in the Loftsmith engine, not printed. Printers vary, so adjust the Joint clearance slider if the quarters bind or rattle.
  • Strength numbers are engine estimates for a hand press of up to about 300 N (roughly 30 kg of force), a 20 N sideways push and the cutter lifted by one edge. It has not been tested on a real printer.
  • It is a large print: about 181 g and just over 4 hours for the full set, split into four plates of about 63 minutes each.
