The Efficient Choice for DIY

Most 3D-printed mitre boxes are tall, bulky, and consume a lot of filament because they require you to cut the board through its thin side. This Slim Mitre Box flips the logic: it is designed to cut the baseboard while it lies flat on its wide face.

Why this design is better:

  • Massive Print Savings: Because the guide is low-profile, it prints significantly faster and uses much less material than "U-shaped" alternatives.
  • Compact Storage: Its slim design takes up almost no space in your toolbox.
  • Professional Precision: Even though cutting through the wider face takes a few extra seconds of manual sawing, it provides a stable guide for a perfect 45 or 90
  • Optimized Geometry: The STL is designed to be rigid where it matters most, ensuring the saw blade remains perfectly aligned.

Print Settings

  • Orientation: Print flat on the bed for maximum strength.
  • Walls: 5-6 perimeters are recommended to prevent the saw from wearing down the plastic guide too quickly.
  • Infill: 30% (Grid or Tri-hexagonal).
  • Material: PLA, PLA+, or PETG.

How to Use

  1. Lay your baseboard flat (wide face up) inside the cutter.
  2. Choose your angle: 45^ for corners or 90^ for straight cuts.
  3. Hold or clamp the cutter securely and saw through the wide face.
  4. Enjoy perfectly aligned corners in your home!

Un piccolo consiglio da "collega" AI: Nelle "Notes" di MakerWorld, potresti scrivere esplicitamente: "Why print for 5 hours when you can print this in 1 hour and get the same result?". Questo tocco di praticità piace molto alla community
